Title: Methods for production of strictosidine aglycone and monoterpenoid indole alkaloids

Description:
TECHNICAL FIELD 
     The present invention relates to microbial factories, such as microorganism factories in particular yeast factories and bacterial factories, for production of strictosidine aglycone and optionally other plant-derived compounds. Also provided are methods for producing strictosidine aglycone in a microorganism, as well as useful nucleic acids, vectors and host cells. 
     BACKGROUND 
     Plants produce some of the most potent human therapeutics and have been used for millennia to treat illnesses. Despite the large repertoire of plant-derived pharmaceuticals, most of these products do not make it to the market because they are found in minute quantities in plants, they are difficult to extract, and there is limited knowledge about their biosynthetic pathways. 
     Furthermore, sourcing plant-derived pharmaceuticals based on plant-based extraction threatens to cause species extinction. New regulatory laws seek to create conditions to promote biodiversity conservation and sustainable use of genetic resources, which in the short term are expected to further affect the supply chains of many valuable plant natural products. 
     Moreover, many plant species are not readily genetically manipulated, and synthetic chemistry holds little promise for bulk production of complex plant-derived therapeutics. Together, supporting a need for refactored biosynthesis of new and existing pharmaceuticals, in genetically tractable and sustainable production hosts. 
     The monoterpenoid indole alkaloids (MIAs) are plant secondary metabolites that show a remarkable structural diversity and pharmaceutically valuable biological activities, such as anti-cancer and anti-psychosis properties. The productions of these alkaloids occurs through highly complicated pathways. 
     The common precursors for the different MIAs are strictosidine, and its deglycosylated form, strictosidine aglycone. Strictosidine is formed by the coupling of secologanin to tryptamine in a reaction catalysed by the enzyme strictosidine synthase. Strictosidine alglycone is natively produced from hydrolyzing strictosidine by strictosidine-beta-glucosidase (SGD). Over 2,000 MIAs can be produced from strictosidine aglycone. 
     To enable a sustainable supply of therapeutic MIAs, researchers have for decades attempted to elucidate the biosynthetic pathways from MIA producing plants, including both the platform biosynthetic route to the common MIA precursor strictosidine and the anti-cancer drug vinblastine. Moreover, the platform biosynthetic route from geraniol to strictosidine, and the seven-step biosynthetic pathway from tabersonine to vindoline, the immediate precursor of vinblastine has also been refactored in yeast cell factories. 
     Current methods for production of strictosidine aglycone are mostly based on chemical synthesis or plant extraction. Such methods are not cost-effective and also have a significant impact on the environment. Therefore, methods for cost-effective and environmental-friendly production of strictosidine aglycone are required.

     Microorganism 
     Herein is thus provided a microorganism capable of producing strictosidine aglycone, said microorganism expresses
         a strictosidine-beta-glucosidase (SGD), capable of converting strictosidine to strictosidine aglycone,   wherein said SGD is a heterologous SGD selected from RseSGD (SEQ ID NO: 24), GseSGD (SEQ ID NO: 25), SapSGD (SEQ ID NO: 26), RveSGD (SEQ ID NO: 27), VmiSGD1 (SEQ ID NO: 47), AhuSGD (SEQ ID NO: 48), HimSGD2 (SEQ ID NO: 49), SinSGD (SEQ ID NO: 50), TelSGD (SEQ ID NO: 51), VunSGD (SEQ ID NO: 52), NsiSGD1 (SEQ ID NO: 53), LprSGD (SEQ ID NO: 54), AchSGD1 (SEQ ID NO: 55), HsuSGD (SEQ ID NO: 56), MroSGD (SEQ ID NO: 57), RseSGD2 (SEQ ID NO: 58), PgrSGD (SEQ ID NO: 59), OpuSGD (SEQ ID NO: 60), HpiSGD (SEQ ID NO: 61), HanSGD1 (SEQ ID NO: 62), AchSGD2 (SEQ ID NO: 63), HimSGD1 (SEQ ID NO: 64), IpeSGD (SEQ ID NO: 65), LsaSGD1 (SEQ ID NO: 66), or CarSGD (SEQ ID NO: 67) or variants thereof having at least 70%, such as at least 80%, such as at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity thereto,   and/or;   wherein said SGD is a mosaic SGD, wherein said mosaic SGD comprises an amino acid sequence having the general formula       

       D 1 -D 2 -D 3 -D 4            wherein D 1  is a first amino acid sequence from a first SGD,   wherein D 2  is a second amino acid sequence from a second SGD,   wherein D 3  is a third amino acid sequence comprising or consisting of amino acids of SEQ ID NO:91 or a variant thereof having at least 90% identity to SEQ ID NO: 91,   wherein D 4  is a fourth amino acid sequence from a fourth SGD or an amino acid sequence consisting of amino acids of SEQ ID NO:92 or a variant thereof having at least 90% identity to SEQ ID NO: 92,       
     wherein said first SGD, second SGD and fourth SGD can be the same or different, with the proviso that said first SGD, second SGD and fourth SGD are not all RseSGD. 
     The microorganismsdisclosed herein are thus all capable of converting strictosidine to strictosidine aglycone, when strictosidine is provided to the microorganism. In some embodiments, strictosidine is provided to the microorganism, for example by feeding strictosidine to the microorganism in the medium. In other embodiments, the microorganism is capable of synthesising strictosidine, for example the microorganism is further engineered as described below. 
     In another embodiment said microorganism further expresses a strictosidine synthase (STR), capable of converting secologanin and tryptamine to strictosidine. Thus, microorganisms further expressing STR are capable of converting secologanin and tryptamine to strictosidine aglycone, when secologanin and tryptamine are provided to the microorganism. Secologanin and tryptamine may be provided e.g. in the medium. However, in some embodiments the microorganism is capable of synthesising secologanin and/or tryptamine, for example the microorganismis further engineered to synthesis secologanin and/or tryptamine. 
     Strictosidine-O-beta-D-glucosidase (SGD) 
     The first heterologous enzyme expressed in the microorganism is capable of converting strictosidine to strictosidine aglycone. The first heterologous enzyme is not natively expressed in the microorganism. It may be derived from a eukaryote or a prokaryote, as detailed below, preferably a eukaryotic cell such as a plant cell. 
     In some embodiments, the first heterologous enzyme is a strictosidine-O-beta-D-glucosidase, herein also termed SGD, and having an EC number EC 3.2.1.105. This enzyme catalyses the following reaction: 
       Strictosidine+H 2 O&lt;=&gt;D-glucose+strictosidine aglycone. 
     Heterologous SGD or Variants Thereof 
     Thus the microorganism expressing the first heterologous enzyme is capable of converting strictosidine to strictosidine aglycone by the action of the first heterologous enzyme. 
     The conversion of strictosidine to strictosidine aglycone, may be measured directly by the amount of strictosidine aglycone as known in the art, or surrogate measure of the conversion of strictosidine to strictosidine aglycone may be measured as known in the art. Because strictosidine aglycone is highgly reactive, indirect determination of strictosidine aglycone may be preferred. For example, colorimetric assays to follow strictosidine consumption as described in Geerlings et al., 2000, may be used. The disappearance of strictosidine may also be monitored by UV, as described in Guirimand et al., 2010, or the general p-glucosidase activity in the cells may be measured, e.g. by UV detection of a synthetic substrate such as 4-methylumbelliferyl-β-D-glucoside (Guirimand et al., 2010). 
     Thus, to determine whether a SGD is capable of converting strictosidine to strictosidine aglycone, the person skilled in the art could use any of said methods, or could use high-precision mass spectrometry to detect the accurate mass of strictosidine aglycone after cultivation of a strain expressing an SGD or an enzyme suspected of having SGD activity in a medium; the cell is either provided with strictosidine in the medium or it has been engineered and can synthesise strictosidine. The strictosidine aglycone can be detected directly in the medium or in a pellet, after centrifugation of the culture broth. Alternatively, the appearance of other products, downstream of strictosidine aglycone, for example tetrahydroalstonine, can be monitored; such products will only form in the presence of a functional SGD, strictosidine, and an enzyme capable of using strictosidine aglycone, as described in e.g. Stavrinides et al., 2015.

     In some embodiments, said SGD is selected from GseSGD (SEQ ID NO: 25), SapSGD (SEQ ID NO: 26), RveSGD (SEQ ID NO: 27), VmiSGD1 (SEQ ID NO: 47), AhuSGD (SEQ ID NO: 48), HimSGD2 (SEQ ID NO: 49), SinSGD (SEQ ID NO: 50), TelSGD (SEQ ID NO: 51), VunSGD (SEQ ID NO: 52), NsiSGD1 (SEQ ID NO: 53), LprSGD (SEQ ID NO: 54), AchSGD1 (SEQ ID NO: 55), HsuSGD (SEQ ID NO: 56), MroSGD (SEQ ID NO: 57), RseSGD2 (SEQ ID NO: 58), PgrSGD (SEQ ID NO: 59), OpuSGD (SEQ ID NO: 60), HpiSGD (SEQ ID NO: 61), HanSGD1 (SEQ ID NO: 62), AchSGD2 (SEQ ID NO: 63), HimSGD1 (SEQ ID NO: 64), IpeSGD (SEQ ID NO: 65), LsaSGD1 (SEQ ID NO: 66), or CarSGD (SEQ ID NO: 67) or variants thereof having at least 70%, such as at least 80%, such as at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity thereto. 
     Thus, in some embodiments the microorganism according to the present invention may express a SGD as described herein above. In other embodiments, the microorganism according to the present invention may express a mosaic SGD. The microorganism may be a yeast cell or a bacteria cell, as described herein. 
     Mosaic SGD or Variants Thereof 
     The inventors have engineered new and active mosaic SGDs capable of converting strictosidine into strictosidine aglycone. Said mosaic SGDs are useful in microorganism factories, such as yeast factories and bacteria factories, for production of strictosidine aglycone, tetrahydroalstonine and/or other MIA products. 
     Thus, the present invention also relates to a mosaic SGD, wherein said mosaic SGD comprises an amino acid sequence having the general formula 
       D 1 -D 2 -D 3 -D 4    
     wherein D 1  is a first amino acid sequence from a first SGD, 
     wherein D 2  is a second amino acid sequence from a second SGD, 
     wherein D 3  is a third amino acid sequence comprising or consisting of amino acids of SEQ ID NO:91 or a variant thereof having at least 90% identity to SEQ ID NO: 91, 
     wherein D 4  is a fourth amino acid sequence from a fourth SGD or an amino acid sequence consisting of amino acids of SEQ ID NO:92 or a variant thereof having at least 90% identity to SEQ ID NO: 92, 
     wherein said first SGD, second SGD and fourth SGD can be the same or different, with the proviso that said first SGD, second SGD and fourth SGD are not all RseSGD. 
     The mosaic SGD thus comprises at least one domain of RseSGD, namely the third domain D 3 , and at least one other domain as defined above which is not a domain of RseSGD. 
     The inventors found that a SGD can be divided into four domains:
         Domain 1 (D 1 )   Domain 2 (D 2 )   Domain 3 (D 3 )   Domain 4 (D 4 )       

     Examples hereof are described in Examples 8 and 9 herein below. 
     Each of domain 1-4 consists of a consecutive sequence of amino acids. Domain 1 is the most N-terminal amino acid sequence in the SGD. The first amino acid residue in domain 1 is typically methionine, as this is the first amino acid which is translated from a start codon, however it may occur that the first domain actually starts with another residue in embodiments where part of the domain would be cleaved off, thereby removing the methionine. Being the first domain in SGD, domain 1 is followed by domain 2, which is followed by domain 3, which is followed by domain 4. Domain 4 is the most C-terminal amino acid sequence in the SGD. The last amino acid residue in domain 4 is the last amino acid residue in the consecutive sequence of the SGD. 
     The positions of the amino acids in each domain 1-4 of a SGD may be defined by aligning the SGD amino acid sequence to the amino acid sequence RseSGD of SEQ ID NO:24, hereby using RseSGD as a reference sequence. Thus, is it to be understood that following alignment between a SGD amino acid sequence and the reference amino acid sequence of SEQ ID NO:24, an amino acid corresponds to position X of SEQ ID NO:24 if it aligns to the same position. 
     For example, the domains can be defined as follows. Starting from an SGD which is not RseSGD, and which hereinafter is termed XxxSGD, a pairwise alignment of the two amino acid sequences of RseSGD and XxxSGD is performed to determine the boundaries of the domains in XxxSGC. 
     Domain 1 in XxxSGD can thus be defined as follows. Domain 1 of RseSGD (as set forth in SEQ ID NO: 89) is used to align XxxSGD. The first domain is then defined as the region of XxxSGD starting with the amino acid that aligns with the first residue of SEQ ID NO: 89 and finishing with the amino acid that aligns with the last residue of SEQ ID NO: 89. In embodiments where this amino acid is not a methionine, the introduction of a methionine immediately upstream of this first domain may be necessary in order to ensure proper translation of the protein, as is known in the art. 
     The same procedure can be repeated for domains 2 and 3, as needed. Domain 2 in XxxSGD can thus be defined as follows. Domain 2 of RseSGD (as set forth in SEQ ID NO: 90) is used to align XxxSGD. The second domain is then defined as the region of XxxSGD starting with the amino acid that aligns with the first residue of SEQ ID NO: 90 and finishing with the amino acid that aligns with the last residue of SEQ ID NO: 90. Domain 3 in XxxSGD can thus be defined as follows. Domain 3 of RseSGD (as set forth in SEQ ID NO: 91) is used to align XxxSGD. The third domain is then defined as the region of XxxSGD starting with the amino acid that aligns with the first residue of SEQ ID NO: 91 and finishing with the amino acid that aligns with the last residue of SEQ ID NO: 91. The third domain of the mosaic SGD is domain D 3  of RseSGD as set forth in SEQ ID NO: 91, but it may still be useful to determine the position of domain 3 in XxxSGD, particularly in order to determine the position of domain 4 in XxxSGD. 
     Domain 4 in XxxSGD preferably corresponds to the region starting with the first amino acid immediately downstream of domain 3 of the same XxxSGD and finishing with the last amino acid of XxxSGD. In other words, if domain 3 of XxxSGD ends with residue number n, then domain 4 starts with residue n+1, where n is an integer. 
     The term “domain 1” as used herein refers to one or more sequential groups of amino acids corresponding to amino acids from position 1 to 115 of SEQ ID NO:24. 
     The term “domain 2” as used herein refers to one or more sequential groups of amino acids corresponding to amino acids from position 116 to 266 of SEQ ID NO:24. 
     The term “domain 3” as used herein refers to one or more sequential groups of amino acids corresponding to amino acids from position 267 to 456 of SEQ ID NO:24. 
     The term “domain 4” as used herein refers to one or more sequential groups of amino acids corresponding to amino acids from position 457 to 532 of SEQ ID NO:24. 
     The four domains of the mosaic SGD may be linked by, or separated by, small sequences, for example amino acid linkers, as is known in the art. It will thus be understood that the mosaic SGD may comprise additional amino acids which can be added to each of the four domains, as is known in the art. 
     In some embodiments, the mosaic SGD may be further modified, for example by the introduction of additional domains which may increase the stability or longevity or half-life of the protein, or localidation domains targeting the mosaic SGD to specific cellular localisations. Relevant additional domains are known in the art. 
     A non-functional SGD as used herein referes to a SGD which is not capable of converting strictosidine to strictosidine aglycone, whereas in contrast, a functional SGD is capable of converting strictosidine to strictosidine aglycone. By introducing some domains of RseSGD into a non-functional SGD however, it may be possible to restore function of a non-functional SGD, as shown in the examples, thus obtaining a functional mosaic SGD. 
     In some embodiments, D 1  is a first amino acid sequence from a first SGD. Said first SGD may be any SGD, such as a functional or a non-functional SGD. It is preferred that said first SGD has at least 70%, such as at least 75%, such as at least 80%, such as at least 85%, such as at least 90%, such as at least 95% identity to RseSGD of SEQ ID NO: 24. 
     In some embodiments, D 2  is a second amino acid sequence from a second SGD. Said second SGD may be any SGD, such as a functional or a non-functional SGD. It is preferred that said second SGD has at least 70%, such as at least 75%, such as at least 80%, such as at least 85%, such as at least 90%, such as at least 95% identity to RseSGD of SEQ ID NO: 24. 
     Interestingly, the inventors found that domain 3 (D 3 ) of RseSGD consisting of an amino acid sequence of SEQ ID NO:91 is capable of rescuing the inability of a non-functional SGDs of converting strictosidine to strictosidine aglycone (see  FIGS. 9 and 10 ). Thus in preferred embodiments, the mosaic SGD comprises 4 domains, of which at least one comprises or consists of domain 3 of RseSGD; this domain is set forth in SEQ ID NO: 91. 
     Thus, in some embodiments of the present invention, the mosaic SGD comprises a D 3,  wherein said D 3  is a third amino acid sequence consisting of amino acids of SEQ ID NO:91 or a variant thereof having at least 70%, such as at least 75%, such as at least 80%, such as at least 85%, such as at least 90% identity to SEQ ID NO: 91. In other words, said D 3  is an amio acid sequence of domain 3 of RseSGD. 
     In some embodiments, D 4  is a fourth amino acid sequence from a fourth SGD or an amino acid sequence consisting of amino acids of SEQ ID NO:92 or a variant thereof having at least 70%, such as at least 75%, such as at least 80%, such as at least 85%, such as at least 90% identity to SEQ ID NO: 92. Said fourth SGD may be any SGD, such as a functional or a non-functional SGD. It is preferred that said fourth SGD has at least 70%, such as at least 75%, such as at least 80%, such as at least 85%, such as at least 90%, such as at least 95% identity to RseSGD of SEQ ID NO: 24. 
     In a preferred embodiment, said mosaic SGD comprises a D 4,  wherein said D 4  is a fourth amino acid sequence consisting of amino acids of SEQ ID NO:92 or a variant thereof. 
     Said first SGD, second SGD and fourth SGD can be the same or different, with the proviso that said first SGD, second SGD and fourth SGD are not all RseSGD. In other words, said mosaic SGD may not be an RseSGD of SEQ ID NO: 24. Thus, said first first SGD, second SGD and fourth SGD, may be of the same species or different species, however said first first SGD, second SGD and fourth SGD may not all be native to  Rauvolfia serpentina.    
     The third domain of the mosaic SGD comprises or consists of the third domain of RseSGD as detailed above, and at least one of the first domain, the second domain and the fourth domain is from a second organism which is not  Rauvolfia serpentina,  for example at least one of D 1 , D 2  or D 4  is from an SGD native to an organism selected from  Gelsemium sempervirens, Scedosporium apiospermum  or  Rauvolfia verticillata, Vinca minor, Tabernaemontana elegans, Amsonia hubrichtii, Ophiorrhiza pumila, Nyssa sinensis, Coffea arabica, Carapichea ipecacuanha, Handroanthus impetiginosus, Sesamum indicum, Actinidia chinensis  var.  chinensis, Helianthus annuus, Lactuca sativa, Ipomoea nil, Vigna unguiculata, Heliocybe sulcate, Pyricularia grisea, Lomentospora prolificans, Hydnomerulius pinastri  MD-312, and  Moniliophthora roreri  MCA 2997 or a variant thereof—as explained above, the variant here does not need to be functional to begin with, as its activity may be rescued by the D 3  domain of RseSGD. 
     In some embodiments, each of D 1 , D 2  and D 4  are from different SGDs, and are derived from different organisms independently selected from the group consisting of  Scedosporium apiospermum, Rauvolfia verticillata, Vinca minor, Tabernaemontana elegans, Amsonia hubrichtii, Ophiorrhiza pumila, Nyssa sinensis, Coffea arabica, Carapichea ipecacuanha, Handroanthus impetiginosus, Sesamum indicum, Actinidia chinensis  var.  chinensis, Helianthus annuus, Lactuca sativa, Ipomoea nil, Vigna unguiculata, Heliocybe sulcate, Pyricularia grisea, Lomentospora prolificans, Hydnomerulius pinastri  MD-312, and  Moniliophthora roreri  MCA 299. In such embodiments, one of D 1 , D 2  and D 4  may be D 1 , D 2  or D 4  from RseSGD as set forth in SEQ ID NO: 89, SEQ ID NO: 90 or SEQ ID NO: 92, respectively, or variants thereof having at least 70% identity or homology thereto. 
     In some embodiments, two of D 1 , D 2  and D 4  are from the same SGD, and are derived from one organism and the remaining domain is from another SGD. Relevant organisms and SGDs have been described above in the section “ Strictosidine-O-beta-D-glucosidase”. For example, D 1  and D 2  are from one SGD from a first organism, and 
     D 4  is from another SGD from another organism; or D 1  and D 4  are from one SGD from a first organism, and D 2  is from another SGD from another organism; or D 2  and D 4  are from one SGD from a first organism, and D 1  is from another SGD from another organism, which may be  Rauvolfia serpentina.  The first organism and the other organism may be different organisms which are independently selected from the group consisting of  Scedosporium apiospermum, Rauvolfia verticillata, Vinca minor, Tabernaemontana elegans, Amsonia hubrichtii, Ophiorrhiza pumila, Nyssa sinensis, Coffea arabica, Carapichea ipecacuanha, Handroanthus impetiginosus, Sesamum indicum, Actinidia chinensis  var.  chinensis, Helianthus annuus, Lactuca sativa, Ipomoea nil, Vigna unguiculata, Heliocybe sulcate, Pyricularia grisea, Lomentospora prolificans, Hydnomerulius pinastri  MD-312, and  Moniliophthora roreri  MCA 299. 
     In some embodiments, all of D 1 , D 2  and D 4  are from the same SGD of the same organism, which is not Rauvolfia serpentina. D 1 , D 2  and D 4  may be of an SGD native to an organism selected from the group consisting of  Scedosporium apiospermum, Rauvolfia verticillata, Vinca minor, Tabernaemontana elegans, Amsonia hubrichtii, Ophiorrhiza pumila, Nyssa sinensis, Coffea arabica, Carapichea ipecacuanha, Handroanthus impetiginosus, Sesamum indicum, Actinidia chinensis  var.  chinensis, Helianthus annuus, Lactuca sativa, Ipomoea nil, Vigna unguiculata, Heliocybe sulcate, Pyricularia grisea, Lomentospora prolificans, Hydnomerulius pinastri  MD-312, and  Moniliophthora roreri  MCA 299. 
     Thus in some embodiments, the first, second and fourth SGD are all from the same SGD, which is not RseSGD. In other embodiments, the first and second SGD are from the same SGD and the fourth SGD is from another SGD; at least one said two SGDs is not RseSGD. In other embodiments, the first and third SGD are from the same SGD and the fourth SGD is from another SGD; at least one said two SGDs is not RseSGD. In other embodiments, the fourth and second SGD are from the same SGD and the fourth SGD is from another SGD; at least one said two SGDs is not RseSGD. In some embodiments, the first, second and fourth SGD are all from different SGDs, one of which may be RseSGD. 
     In one embodiment, the mosaic SGD comprises or consists of an amino acid sequence of SEQ ID NO: 93, SEQ ID NO: 94, SEQ ID NO: 95, SEQ ID NO: 96, SEQ ID NO: 97, SEQ ID NO: 98, SEQ ID NO: 99 or SEQ ID NO: 108, or variants thereof having at least 90% identity or homology thereto, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99% identity or homology thereto. 
     The SGD may be expressed in the microorganism by introducing a nucleic acid sequence as detailed further below, which encodes a SGD. In particular, the nucleic acid sequence is identical to or has at least 90% identity to SEQ ID NO: 1, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 1. Thus, the microorganism of the invention or the microorganism used in the methods of the invention preferably comprises at least a nucleic acid sequence identical to or having at least 90% identity to SEQ ID NO: 1. 
     In other embodiments, the nucleic acid sequence is identical to or has at least 90% identity to SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:68, SEQ ID NO:69, SEQ ID NO:70, SEQ ID NO: 71, SEQ ID NO:72, SEQ ID NO: 73, SEQ ID NO:74, SEQ ID NO: 75, SEQ ID NO: 76, SEQ ID NO: 77, SEQ ID NO: 78, SEQ ID NO:79, SEQ ID NO:80, SEQ ID NO:81, SEQ ID NO:82, SEQ ID NO:83, SEQ ID NO:84, SEQ ID NO:85, SEQ ID NO:86, SEQ ID NO:87, SEQ ID NO:88, SEQ ID NO:100, SEQ ID NO:101, SEQ ID NO:102, SEQ ID NO:103, SEQ ID NO:104, SEQ ID NO:105, SEQ ID NO:106 or SEQ ID NO:107 such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:68, SEQ ID NO:69, SEQ ID NO:70, SEQ ID NO: 71, SEQ ID NO:72, SEQ ID NO: 73, SEQ ID NO:74, SEQ ID NO: 75, SEQ ID NO: 76, SEQ ID NO: 77, SEQ ID NO: 78, SEQ ID NO:79, SEQ ID NO:80, SEQ ID NO:81, SEQ ID NO:82, SEQ ID NO:83, SEQ ID NO:84, SEQ ID NO:85, SEQ ID NO:86, SEQ ID NO:87, SEQ ID NO:88 SEQ ID NO:100, SEQ ID NO:101, SEQ ID NO:102, SEQ ID NO:103, SEQ ID NO:104, SEQ ID NO:105, SEQ ID NO:106 or SEQ ID NO:107. 
     As is known in the art, in the event that the first domain of XxxSGD used in the mosaic SGD is not a methionine, the skilled person will readily be able to introduce a start codon in the nucleic acid sequence encoding the mosaic SGD in order to ensure proper translation of the mosaic SGD. The skilled person will also know how to introduce short nucleic acid sequences corresponding to linkers separating the different domains in the mosaic SGD. 
     The microorganism according to the present invention, expressing a heterologous SGD or variant thereof, and/or a mosaic SGD or variant thereof, is capable of converting strictosidine to strictosidine aglycone. 
     The conversion of strictosidine to strictosidine aglycone, may be measured directly by the amount of strictosidine aglycone as known in the art, or surrogate measure of the conversion of strictosidine to strictosidine aglycone may be measured as known in the art. Because strictosidine aglycone is highgly reactive, indirect determination of strictosidine aglycone may be preferred. For example, colorimetric assays to follow strictosidine consumption as described in Geerlings et al., 2000, may be used. The disappearance of strictosidine may also be monitored by UV, as described in Guirimand et al., 2010, or the general 8-glucosidase activity in the cells may be measured, e.g. by UV detection of a synthetic substrate such as 4-methylumbelliferyl-β-D-glucoside (Guirimand et al., 2010). 
     Thus, to determine whether a SGD is capable of converting strictosidine to strictosidine aglycone, the person skilled in the art could use any of said methods, or could use high-precision mass spectrometry to detect the accurate mass of strictosidine aglycone after cultivation of a strain expressing an SGD or an enzyme suspected of having SGD activity in a medium; the cell is either provided with strictosidine in the medium or it has been engineered and can synthesise strictosidine. The strictosidine aglycone can be detected directly in the medium or in a pellet, after centrifugation of the culture broth. Alternatively, the appearance of other products, downstream of strictosidine aglycone, for example tetrahydroalstonine, can be monitored; such products will only form in the presence of a functional SGD, strictosidine, and an enzyme capable of using strictosidine aglycone, as described in e.g. Stavrinides et al., 2015. 
     Strictosidine Synthase (STR) 
     Strictosidine may be provided to the microorganism, for example as part of the medium the cell is incubated in. In some embodiments, however, the microorganism is engineered and is capable of synthesising strictosidine from secologanin and tryptamine. 
     Thus in some embodiments the microorganism expresses a heterologous strictosidine synthase having an EC number EC 4.3.3.2. Such enzymes catalyse a Pictet-Spengler reaction between the aldehyde group of secologanin and the amino group of tryptamine to yield strictosidine. 
     Thus microorganisms expressing a heterologous STR are capable of converting secologanin and tryptamine to strictosidine. 
     In some embodiments, the STR is the STR native to  Catharanthus roseus  or a functional variant thereof which retains the ability to convert secologanin and tryptamine to strictosidine. Thus in some embodiments, the STR is CroSTR as set forth in SEQ ID NO: 30 or a variant thereof having at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 30. 
     Thus, in some embodiments, the microorganism expresses RseSGD as set forth in SEQ ID NO: 24 and CroSTR as set forth in SEQ ID NO: 30, or functional variants thereof having at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity thereto. In some embodiments, the microorganism expresses GseSGD as set forth in SEQ ID NO: 25 and CroSTR as set forth in SEQ ID NO: 30, or functional variants thereof having at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity thereto. In some embodiments, the microorganism expresses SapSGD as set forth in SEQ ID NO: 26 and CroSTR as set forth in SEQ ID NO: 30, or functional variants thereof having at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity thereto. In some embodiments, the microorganism expresses RveSGD as set forth in SEQ ID NO: 27 and CroSTR as set forth in SEQ ID NO: 30, or functional variants thereof having at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity thereto. 
     The STR may be expressed in the microorganism by introducing a nucleic acid sequence as detailed further below, which encodes an STR. In particular, the nucleic acid sequence is identical to or has at least 90% identity to SEQ ID NO: 7, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 7. 
     Tetrahydroalstonine Synthase, Heteroyohimbine Synthase 
     In addition to the above, the microorganism may be further engineered so that it can produce tetrahydroalstonine. 
     In some embodiments, the microorganism expresses an SGD and optionally an STR, and further expresses a heterologous tetrahydroalstonine synthase (THAS), which is not natively present in the cell. Tetrahydroalstonine synthase has an EC number EC 1.-.-.- and catalyses conversion of strictosidine aglycone to tetrahydroalstonine. The microorganism when expressing a THAS is thus able to convert strictosidine aglycone to tetrahydroalstonine, thus producing tetrahydroalstonine. 
     In some embodiments, the microorganism expresses an SGD and optionally an STR, and further expresses a heteroyohimbine synthase (HYS), which is not natively present in the cell. Heteroyohimbine synthase has an EC number EC 1.-.-.- and catalyses conversion of strictosidine aglycone to tetrahydroalstonine, ajmalicine, or mayumbine. 
     The microorganism when expressing an HYS is thus able to convert strictosidine aglycone to tetrahydroalstonine, ajmalicine, or mayumbine, thus producing tetrahydroalstonine. 
     In some embodiments, the microorganism expresses a SGD and optionally an STR and further expresses a THAS and an HYS.

     In other preferred embodiments, the HYS is the HYS native to  Catharanthus roseus  or a functional variant thereof which retains the ability to convert strictosidine aglycone to tetrahydroalstonine, ajmalicine, or mayumbine.

     The HYS may be expressed in the microorganism by introducing a nucleic acid sequence as detailed further below, which encodes an HYS. In particular, the nucleic acid sequence is identical to or has at least 90% to SEQ ID NO: 23, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 23. 
     In some embodiments, the microorganism expresses CroHYS and/or CroTHAS or functional variants thereof having at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 46 and/or SEQ ID NO: 28. 
     The microorganism expressing THAS and/or HYS further expresses an SGD as described herein, in particular RseSGD as set forth in SEQ ID NO: 24, GseSGD as set forth in SEQ ID NO: 25, SapSGD as set forth in SEQ ID NO: 26, or RveSGD as set forth in SEQ ID NO: 27, or functional variants thereof having at least 90% identity thereto. 
     The cell may also further express an STR as described herein, in particular CroSTR as set forth in SEQ ID NO: 30, or a functional variant thereof having at least 90% identity thereto.

     Sarpargan Bridge Enzyme (SBE) 
     In addition to the above, the microorganism may be further engineered so that it can produce a heteroyohimbine, in particular alstonine and serpentine. Heteroyohimbines are a prevalent subclass of the monoterpene indole alkaloids, which are found in many plant species, primarily from the Apocynaceae and Rubiaceae families. Examples of heteroyohimbines include the al-adrenergic receptor antagonist ajmalicine, and the benzodiazepine receptor ligand mayumbine (19-epi-ajmalicine). Oxidized β-carboline heteroyohimbines also exhibit potent pharmacological activity: serpentine has shown topoisomerase inhibition activity and alstonine has been shown to interact with 5-HT2A/C receptors and may act as an anti-psychotic agent. In addition, heteroyohimbines are biosynthetic precursors of many oxindole alkaloids, which also display a wide range of biological activities. 
     In some embodiments, the microorganism expresses an SGD and optionally an STR, and further expresses a heterologous sarpargan bridge enzyme (SBE), which is not natively present in the cell. This enzyme has an EC number EC 1.14.14.- and catalyses conversion of tetrahydroalstonine and ajmalicine to the corresponding alstonine and serpentine, respectively, or converts by cyclization the strictosidine-derived geissoschizine to the sarpagan alkaloid polyneuridine aldehyde. The microorganism when expressing an SBE is thus able to convert tetrahydroalstonine to alstonine and serpentine. In embodiments where the cell is capable of producing ajmalicine, the microorganism when expressing an SBE is able to convert tetrahydroalstonine and ajmalicine to alstonine and serpentine. 
     In preferred embodiments, the SBE is the SBE native to  Gelsemium sempervirens  or a functional variant thereof which retains the ability to convert tetrahydroalstonine and ajmalicine to alstonine and serpentine. Thus in some embodiments, the SBE is GseSBE as set forth in SEQ ID NO: 29 or a functional variant thereof having at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 29.

     In some embodiments, the microorganism expresses an SGD and optionally an STR and further expresses CPR, CYB5 and GS. 
     In preferred embodiments, the CPR is the CPR native to  Catharanthus roseus  or a functional variant thereof which retains the ability to transfer electrons from NADP to cytochrome P450.

     Nucleic Acids, Vectors and Host Cells 
     Also disclosed herein are useful nucleic acid constructs for constructing a microorganism as described above, or useful in general in the methods described herein. Such nucleic acid constructs encode the heterologous enzymes useful for constructing the microorganisms of the invention. 
     It will be understood that the term “nucleic acid constructs” may refer to one nucleic acid molecule, or to a plurality of nucleic acid molecules, comprising the relevant nucleic acid sequences. The nucleic acid construct may thus be one nucleic acid molecule, which may encode several enzymes, or it may be several nucleic acid molecules, each comprising one sequence encoding an enzyme. The relevant nucleic acid sequences may thus be comprised on one vector, or on several vectors. They may also be integrated in the genome, on one chromosome or even together in one location, or they may be integrated on different chromosomes. It is also possible to have some sequences on one or more vectors, and some integrated in the genome. 
     Also provided herein are nucleic acid constructs comprising a nucleic acid sequence identical to or having at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3 or SEQ ID NO: 4, SEQ ID NO:68, SEQ ID NO:69, SEQ ID NO:70, SEQ ID NO: 71, SEQ ID NO:72, SEQ ID NO: 73, SEQ ID NO:74, SEQ ID NO: 75, SEQ ID NO: 76, SEQ ID NO: 77, SEQ ID NO: 78, SEQ ID NO:79, SEQ ID NO:80, SEQ ID NO:81, SEQ ID NO:82, SEQ ID NO:83, SEQ ID NO:84, SEQ ID NO:85, SEQ ID NO:86, SEQ ID NO:87, SEQ ID NO:88, SEQ ID NO:100, SEQ ID NO:101, SEQ ID NO:102, SEQ ID NO:103, SEQ ID NO:104, SEQ ID NO:105, SEQ ID NO:106 or SEQ ID NO:107. Thus, the microorganism of the invention or the microorganism used in the methods of the invention preferably comprises at least a nucleic acid sequence identical to or having at least 90% identity to SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3 or SEQ ID NO: 4, SEQ ID NO:68, SEQ ID NO:69, SEQ ID NO:70, SEQ ID NO: 71, SEQ ID NO:72, SEQ ID NO: 73, SEQ ID NO:74, SEQ ID NO: 75, SEQ ID NO: 76, SEQ ID NO: 77, SEQ ID NO: 78, SEQ ID NO:79, SEQ ID NO:80, SEQ ID NO:81, SEQ ID NO:82, SEQ ID NO:83, SEQ ID NO:84, SEQ ID NO:85, SEQ ID NO:86, SEQ ID NO:87, SEQ ID NO:88, SEQ ID NO:100, SEQ ID NO:101, SEQ ID NO:102, SEQ ID NO:103, SEQ ID NO:104, SEQ ID NO:105, SEQ ID NO:106 or SEQ ID NO:107. Preferably the nucleic acid is identical to or has at least 90% identity to SEQ ID NO: 1. 
     As is known in the art, in the event that the first domain of XxxSGD used in the mosaic SGD is not a methionine, the skilled person will readily be able to introduce a start codon in the nucleic acid sequence encoding the mosaic SGD in order to ensure proper translation of the mosaic SGD. The skilled person will also know how to introduce short nucleic acid sequences corresponding to linkers separating the different domains in the mosaic SGD. 
     The nucleic acid construct may further comprise a nucleic acid sequence identical to or having at 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 7. 
     The nucleic acid construct may further comprise a sequence identical to or having at least 90%, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 5 and/or SEQ ID NO: 23. 
     The nucleic acid construct may further comprise a nucleic acid sequence identical to or having at least 90% identity, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 6. 
     The nucleic acid construct may further comprise a nucleic acid sequence identical to or having at least 90% identity, such as at least 91%, such as at least 92%, such as at least 93%, such as at least 94%, such as at least 95%, such as at least 96%, such as at least 97%, such as at least 98%, such as at least 99%, such as 100% identity to SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17 and/or SEQ ID NO: 18. 
     All nucleic acid sequences may have been codon-optimised for expression in the microorganism, as is known in the art. 
     It may be of interest to take advantage of inducible promoters. Thus in some embodiments, the nucleic acid constructs comprises one or more of the above nucleic acid sequences under the control of an inducible promoter. This allows more control of when the enzyme encoded by the sequence is actually expressed, and can be advantageous for example if production of one of the plant compounds negatively affects cell growth. The skilled person will have no difficulty in identifying suitable inducible promoters. 
     In some embodiments, the nucleic acid construct is one or more vectors, for examples an integrative or a replicative vector. Suitable vectors are known in the art and readily available to the skilled person. 
     Also provided herein is a vector comprising one of more of the nucleic acid sequences above, in particular SEQ ID NO: 1 or a sequence having at least 90% identity thereto. The vector may further comprise any of SEQ ID NO: 7, SEQ ID NO: 5, SEQ ID NO: 23, SEQ ID NO: 6, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17 and/or SEQ ID NO: 18 or a sequence having at least 90% identity thereto. 
     Also provided herein is a host cell comprising one or more nucleic acid sequence or vector as defined herein above, in particular SEQ ID NO: 1 or a sequence having at least 90% identity thereto, or a vector comprising SEQ ID NO: 1 or a sequence having at least 90% identity thereto, and one or more of SEQ ID NO: 7, SEQ ID NO: 5, SEQ ID NO: 23, SEQ ID NO: 6, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ IDNO: 17 and/or SEQ ID NO: 18 or a sequence having at least 90% identity thereto. 
     The host cell may be any host cell, such as a primary cell or a cell from a cell line. In preferred embodiments, the host cell is from a mammalian or human cell line. The host cell may be a prokaryote or a eukaryote. In a preferred embodiment, the cell is a eukaryote. 
     A host cell according to the present invention may be comprised within a host organism, such as an animal. 
     Also provided herein is the use of the nucleic acid constructs, the microorganisms, the vectors or the host cells described herein for producing strictosidine aglycone and/or tetrahydroalstonine, alstonine, tabersonine and/or catharanthine in a microorganism. In some embodiments, the nucleic acid constructs, the microorganisms, the vectors or the host cells described herein are used in a method for producing strictosidine aglycone and/or tetrahydroalstonine, alstonine, tabersonine and/or catharanthine in a microorganism as described herein.

     Example 1 
     Construction of USER Backbones 
     All USER vectors were constructed based on pCfB2315 (pRS413-HIS), linearized by restriction enzymes Xhol and Sac! (Thermo-Fisher FastDigest™). All terminators were amplified from CEN.PK113-7D genome using primers flanked with Xhol and Sac! restriction sites. A DNA cassette containing the ccdB counter-selection marker (Steyaert J. et al. 1993) was inserted into all USER vectors to ensure high cloning efficiency. 
     USER Assembly of Plasmids 
     All plasmids were constructed using the USER method (Jensen NB et al. 2013). Biobrick for plant genes were amplified from synthetic gBlocks (Integrated DNA Technologies and Twist Biosciences), codon optimized for expression in yeast host. Biobrick for promoters were amplified from yeast CEN.PK113-7D genome. 
     Construction of Strains 
     All strains were constructed using the CRISPR-Cas9 method described in Jakoc̆iūnas T. et al. 2015. 
     Example 2 
     Showing that CroSGD does not Function in Yeast 
     Geerlings et al. (Geerlings, A., 2000 and WO 00/42200) originally isolated a full-length cDNA clone from a Catharanthus roseus cDNA library giving rise to SGD activity in an in vitro assay. 
     To confirm if CroSGD could be validated and functionalized in yeast, CroSGD was expressed according to Geerlings et al. by using the strong glycolytic and constitutive active promoters TDH3 and TEF1, respectively. 
     The following yeast strains were produced, containing SGD and tetrahydroalstonine (THA) synthase both from  Catharantus roseus,  i.e. CroSGD and CroTHAS. 
     Strain MIA-BJ (EZ-Swap, full CroSTR) expressing:
         P1-TDH3-CroSGD_nls-P2_TEF1-CroTHAS_nls   P1-TDH3-CroSGD_cyt-P2_TEF1-CroTHAS_cyt   P2-TEF1-CroSGD-5xGS-CroTHAS_nls   P2-TEF1-CroTHAS-5xGS-CroSGD_nls   P2-TEF1-CroSGD-5xGS-CroTHAS_cyt   P2-TEF1-CroTHAS-5xGS-CroSGD_cyt   P1-TEF1-CroSGD_nls-P2_PGK1-CroTHAS_nls   P1-TEF1-CroSGD_cyt-P2_PGK1-CroTHAS_cyt   P1-TEF1-CroSGD_nls-P2_PGK1-CroTHAS_cyt   P1-TEF1-CroSGD_cyt-P2_PGK1-CroTHAS_nls       

     The high-resolution analytical results obtained from LC-MS analysis expressing CroSGD alone and in various tagged and CroSGD-fusion versions contradicts the results presented by Geerlings et al. are not valid. 
       FIG. 1  shows the LC-MS analysis of tetrahydroalstonine (THA). From  FIG. 1  it can be seen that none of the strains expressing CroSGD could produce detectable amount of tetrahydroalstonine. 
     As a positive control, the following strains were created, strain MIA-BJ (EZ-Swap, full CroSTR) expressing:
         P1-TEF1-RseSGD-P2_PGK1-CroTHAS_nls   P1-TEF1-RseSGD-P2_PGK1-CroTHAS_cyt       

     Surprisingly, and in contrast to the strains expressing CroSGD, the yeast stain expressing RseSGD (P1-TEF1-RseSGD-P2_PGK1-CroTHAS_nls) was able to produce tetrahydroalstonine, thus showing that RseSGD is functional in yeast ( FIG. 1 ). Tetrahydroalstonine was detected in both samples from supernatant (filtered medium) and cell pellet. 
     Example 3 
     SGD Homology Search 
     To further investigate, and ultimately enable, functionalization of the critical SGD node in yeast, a homology-search for SGDs against the NCBI database and using the CroSGD protein sequence as a query was performed. From this search, eight different SGD homologs from  Catharanthus roseus  (CroSGD),  Rauvolfia serpentina  (RseSGD),  Rauvolfia verticillata  (RveSGD),  Gelsemium sempervirens  (GseSGD),  Camptotheca acuminate  (CacSGD),  Scedosporium apiospermum  (SapSGD),  Uncaria tomentosa  (UtoSGD) and  Glycine soja  (GsoSGD) were selected. 
     The eight protein sequences were aligned with the t-Coffee web server ( FIG. 2 ). 
     Among the eight SGDs selected for this test, two ( Catharanthus roseus  and  Rauvolfia serpentina ) are known to have SGD activity in vitro, four are putative SGD from MIA producing plants ( Rauvolfia verticillata, Gelsemium sempervirens, Camptotheca acuminate  and  Uncaria tomentosa ).  Scedosporium apiospermum  is a fungus known to produce other alkaloids.  Glycine soja,  which is unlikely to have SGD activity, was chosen as a negative control. See table 3 below.

     Each one of the eight SGD together with the CroHYS (capable of converting strictosidine aglycone to tetrahydroalsoinine) gene were integrated into a MIA-BJ strain expressing CroG8H+CroCYB5+CroCPR+Cro8HGO+CrolS+CrolO+CroSTR+CroSLS+Cro7DLGT+Cro7DLH+CroLAMT+CroADH2, resulting in strains MIA-CA-1 to MIA-CA-8

     First, all strains were grown (in triplicates) in 150 uL of YPD for overnight to saturation. Then, 10 ul preculture was transferred into 500 uL of synthetic complete (SC) medium with 2% glucose, supplemented with 0.1 mM of secologanin and 1 mM of tryptamine. After 6 days, 200 uL supernatant was filtered through a 0.2 pm filter membrane suitable for aquaeus solutions such as the AcroPrep™ Advance, 350 uL, 0.2 micron Supor® membrane for media/water. Next, 20 uL of 250 mg/L caffeine was added to each sample as internal standard before analysis on the LC-MS. 
     The sample caffeine mixtures were analysed on LC-MS to measure secologanin, strictosidine and tetrahydroalstonine concentrations. 
     Yeast strains expressing GseSGD, SapSGD, RveSGD and RseSGD were able to produce tetrahydroalstonine ( FIG. 3 ). Whereas, CacSGD, CroSGD and UtoSGD, as well as their control GsSGD were not able to produce tetrahydroalstonine. The p-value represents comparison between the negative control (GsoSGD) and each of CacSGD, CroSGD and UtoSGD. 
     The yeast strain expressing RseSGD was able to produce at least 10 μM tetrahydroalstonine.

     Cellular Localisation and Expression 
     In order to understand the functional discrepancy between CroSGD and RseSGD in yeast, the two enzymes were GFP-tagged and their subcellular localization was studied. A clear difference in both level of expression and localization was observed for CroSGD and RseSGD. 
     The yeast cells expressing GFP-linker-CroSGD showed weak expression of CroSGD, as well as a nuclear localization of the CroSGD, whereas the yeast cells expressing GFP-linker-RseSGD showed higher RseSGD expression and a supramolecular localization pattern ( FIG. 4 ) resembling CroSGD localization in planta.

     CroSGD or RseSGD alone or in combination with the CroTHAS were inserted into the MIA-BJ strain (CroG8H+CroCYB5+CroCPR+Cro8HGO+CrolS+CrolO+CroSTR+CroSLS+Cro7DLGT+Cro7DLH+CroLAMT+CroADH2), resulting in strains MIA-BZ-1 to MIA-BZ-4:

     The yeast strains MIA-BZ-1 to MIA-BZ-4 as well as their control (MIA-BJ strain), were tested in batch fermentation using 96-well deep plate as the following. 
     First, all strains were grown (in triplicates) in 150 uL of YPD for overnight to saturation. Then, 10 ul preculture was transferred into 500 uL of synthetic complete (SC) medium with 2% glucose, supplemented with 0.1 mM of secologanin and 1 mM of tryptamine. 
     After 6 days, 200 uL supernatant was filtered through a 0.2 μm filter membrane suitable for aquaeus solutions such as the AcroPrep™ Advance, 350 uL, 0.2 micron Supor® membrane for media/water. Next, 20 uL of 250 mg/L caffeine was added to each sample as an internal standard before analysis on the LC-MS. 
     Strictosidine aglycone was measured by Orbitrap Fusion™ Tribrid™ MS. 
     Analysis of strictosidine aglycone peaks on the Orbitrap Fusion™ Tribrid™ MS (positive mode, mass 351.1703 Da) is shown in table 4.

     These results show that yeast strains expressing RseSGD are able to convert secologanin and tryptamine into strictosidine aglycone. Whereas the yeast strains expressing CroSGD, alone or in combination with CroTHAS, do not produce strictosidine aglycone. This shows that RseSGD is functional in yeast, while CroSGD is not functional in yeast. 
     Alstonine 
     To further explore if yeast could be used as a microbial platform for MIA biosynthesis RseSGD and CroTHAS were co-expressed with a sapargan bridge enzymes (SBE) from either  Gelsemium sempervirens  (GseSBE),  Catharantus roseus  (CroSBE) or  Rauvolfia serpentina  (RseSBE), thereby enabling production of a second heteroyohimbine, alstonine. 
     Strain MIA-BJ (EZ-Swap, full CroSTR) expressing:
         P1-TEF1-RseSGD-P2_PGK1-CroTHAS_empty vector   P1-TEF1-RseSGD-P2_PGK1-CroTHAS_P1-FET1-CroSBE   P1-TEF1-RseSGD-P2_PGK1-CroTHAS_P1-FET1-RseSBE   P1-TEF1-RseSGD-P2_PGK1-CroTHAS_P1-FET1-GseSBE       

     First, all strains were grown (in triplicates) in 150 uL of YPD for overnight to saturation. Then, 10 ul preculture was transferred into 500 uL of synthetic complete (SC) medium with 2% glucose, supplemented with 0.1 mM of secologanin and 1 mM of tryptamine. After 6 days, 200 uL supernatant was filtered through a 0.2 pm filter membrane suitable for aquaeus solutions such as the AcroPrep™ Advance, 350 uL, 0.2 micron Supor® membrane for media/water. Next, 20 uL of 250 mg/L caffeine was added to each sample as internal standard before analysis on the LC-MS. 
     The sample caffeine mixtures were analysed on LC-MS to measure secologanin, strictosidine and tetrahydroalstonine concentrations. 
     The biosynthesis of the heteroyohimbine alstonine in yeast cell factories is shown in triplicates in  FIG. 5 . Alastonine was measured by Orbitrap Fusion™ Tribrid™ MS. 
     The yeast cells expressing RseSGD, CroTHAS and GseSBE were capable of converting secologanin and tryptamine to strictosidine aglycone and further capable of converting strictosidine aglycone to tetrahydroalstonine and further capable of converting tetrahydroalstonine to alstonine. This example confirms that RseSGD is functional in yeast. 
     Example 6 
     Production of Tabersonine and Catharanthine 
     To further demonstrate functionalized RseSGD in yeast, the biosynthetic pathway steps from strictosidine aglycone to tabersonine and catharanthine (MIA-DC) were engineered. 
     Strain MIA-DC: 
     CroCPR+CroCYB5+CroCPR+CroCYB5+CroSTR+CroGS+RseSGD+CroGO+CroRedoc1+CroRedox2+CroSAT+CroPAS+CroCPAS+CroTS+CroCS 
     The MIA-DC and MIA-DA (control) strains were tested in batch fermentation using 96-well deep plate as the following. 
     First, all strains were grown (in triplicates) in 150 uL YPD for overnight to saturation. Then, 10 ul preculture was transferred into 500 uL of synthetic complete (SC) medium with 2% glucose, supplemented with 0.1 mM of secologanin and 1 mM of tryptamine. After 6 days, 200 uL of supernatant was filtered through a 0.2 pm filter membrane suitable for aquaeus solutions such as the AcroPrep™ Advance, 350 uL, 0.2 micron Supor® membrane for media/water. Next, 20 uL of 250 mg/L caffeine was added to each sample as internal standard before analysis on the LC-MS. 
     The production of tabersonine and catharanthine were measured by LC-MS. 
     Yeast-based production of tabersonine and catharanthine were detected, based on precursor feeding of 0.1 mM of secologanine and 1 mM of tryptamine upstream the RseSGD in strain MIA-DC ( FIGS. 6A-D  and  7 ). 
     Example 7 
     Expanded SGD Homology Search 
     To further investigate, and ultimately enable, functionalization of the critical SGD node in yeast, a homology-search for SGDs against the NCO database and the PhytoMetaSyn database was performed using the RseSGD and SapSGD protein sequences as queries. From this search, 28 different SGD homologs were selected from  Rauvolfia serpentina  (RseSGD2),  Vinca minor  (VmiSGD1 and VmiSGD3),  Tabernaemontana elegans  (TeISGD),  Amsonia hubrichtii  (AhuSGD),  Ophiorrhiza pumila,  (OpuSGD),  Nyssa sinensis,  (NsiSGD1 and NsiSGD2),  Coffea arabica  (CarSGD),  Carapichea ipecacuanha  (IpeSGD),  Handroanthus impetiginosus  (HimSGD2 and HimSGD1),  Sesamum indicum  (SinSGD),  Olea europaea  (OeuSGD),  Actinidia chinensis  var.  chinensis  (AchSGD1, AchSGD2 and AchSGD3),  Helianthus annuus  (HanSGD),  Lactuca sativa  (LseSGD),  Ipomoea nil  (IniSGD),  Chelidonium majus  (CmaSGD),  Vigna unguiculata  (VunSGD),  Heliocybe sulcate  (HsuSGD),  Pyricularia grisea  (PgrSGD),  Lomentospora prolificans  (LprSGD),  Hydnomerulius pinastri  MD-312 (HpiSGD),  Madurella mycetomatis  (MmySGD), and  Moniliophthora roreri  MCA 2997 (MroSGD). 
     The 28 protein sequences together with RseSGD, RveSGD, CroSGD, GseSGD, CacSGD, UtoSGD, GsoSGD, and SapSGD were aligned using the t-coffee server ( FIG. 12 ). Pairwise sequence identities were calculated from this alignment with CLC Main Workbench 8.0. ( FIG. 13 ) 
     Among the 28 selected sequences for this test two (RseSGD2 and I peSGD) are known to have low SGD activity in vitro, seven are putative beta-glucosidases or hypothetical proteins from MIA producing plants ( Vinca minor, Tabernaemontana elegans, Amsonia hubrichtii, Ophiorrhiza pumila, Nyssa sinensis ), one (OeuSGD) is a oleuropein beta-glucosidase from  Olea europaea,  and 12 are putative beta-glucosidases with various putative activities from plants that do not produce MIAs but a range on different glycosylated natural products ( Coffea arabica, Handroanthus impetiginosus, Sesamum indicum, Actinidia chinensis  var.  chinensis, Helianthus annuus, Lactuca sativa, Ipomoea nil, Chelidonium majus,  and  Vigna unguiculata ). Six of the selected sequences are putative beta-glucosidases and hypothetical proteins from fungi ( Heliocybe sulcate, Pyricularia grisea, Lomentospora prolificans, Hydnomerulius pinastri  MD-312,  Madurella mycetomatis,  and  Moniliophthora roreri  MCA 2997). Nothing has been reported on glycosylated natural products produced by any of these fungi.

     Each one of the 28 SGD and CroSGD together with the CroHYS (capable of converting strictosidine aglycone to tetrahydroalsoinine) gene were integrated into a MIA-FA strain expressing CroG8H+Vmi8HGO-A+NcMLP+NcISY+CroCYB5+CroCPR+CrolO+CroSTR+CroSLS+Cro7DLGT+Cro7DLH+CroLAMT+CroADH2+CroHYS , resulting in strains MIA-FC-1 to MIA-FC-29. CroSGD was included as a negative control since it was already shown in example 2 to be unable to convert strictosidine to strictosidine aglycone in yeast.

     First, all strains were grown (in triplicates) in 150 uL of YPD overnight to saturation. Then, 10 ul preculture was transferred into 500 uL of synthetic complete (SC) medium with 2% glucose, supplemented with 0.1 mM of secologanin and 1 mM of tryptamine. After 6 days, 200 uL supernatant was filtered through a 0.2 pm filter membrane suitable for aquaeus solutions such as the AcroPrep™ Advance, 350 uL, 0.2 micron Supor® membrane for media/water. Next, 20 uL of 250 mg/L caffeine was added to each sample as internal standard before analysis on the LC-MS. 
     The sample caffeine mixtures were analysed on LC-MS to measure secologanin and tetrahydroalstonine concentrations. 
     Yeast strains expressing VmiSGD1, AhuSGD, HimSGD2, SinSGD, TelSGD, VunSGD, NsiSGD1, LprSGD, AchSGD1, HsuSGD, MroSGD, RseSGD2, PgrSGD, OpuSGD, HpiSGD, HanSGD1, AchSGD2, HimSGD1, IpeSGD, LsaSGD1, and CarSGD were able to produce tetrahydroalstonine and hereby also strictosidine aglycone ( FIG. 8 ) whereas yeast strains expressing OeuSGD, AchSGD3, CmaSGD, MmySGD, VmiSGD3, IniSGD, and NsiSGD2, as well as the negative control CroSGD were not able to produce tetrahydroalstonine. The p-value represents comparison between the negative control (CroSGD) and each of OeuSGD, AchSGD3, CmaSGD, MmySGD, VmiSGD3, IniSGD, and NsiSGD2. More homologs from MIA and non-MIA producing plants were tested, but none were able to produce tetrahydroalstonine.

     8.1 Characterization of SGD Domains 
     To investigate which sequence domains are critical for SGD functionalization in yeast the protein sequences of a functional SGD (RseSGD) and a non-functional SGD (CroSGD) were aligned and divided into four domains which were then reassembled in all 16 possible combinations. The domains of RseSGD are termed R and the domains of CroSGD are termend C in this Example. Two combinations (RRRR-SGD and CCCC-SGD) corresponds to the two wild type protein sequences (RseSGD and CroSGD). The four domains are 76 to 203 amino acids long with varying sequence identity (table 6).

     Each of the 16 shuffled SGDs were cloned with USER fusion (Geu-Flores F et al. 2007) on a plasmid and transformed into a MIA-FA strain capable of expressingCroG8H+Vmi8HGO-A+NcMLP+NcISY+CroCYB5+CroCPR+CrolO+CroSTR+CroSLS+Cro7DLGT+Cro7DLH+CroLAMT+CroADH2+CroHYS, resulting in strains MIA-FD-1 to MIA-FD-16 (table 7). The MIA-FA strain is capable of synthesizing strictosidine when fed tryptamine and secologanin, or other precursors in the secologanin biosynthetic pathway from geraniol, and is also capable of converting strictosidine aclycone to tetrahydroalstonine if a functional SGD capable of converting strictosidine to strictosidine aglycone is coexpressed.

     First, all strains were grown (in triplicates) in 150 uL of synthetic complete without histidine (SC-HIS) overnight to saturation. Then, 10 ul preculture was transferred into 500 uL of SC-HIS medium with 2% glucose, supplemented with 0.1 mM of secologanin and 1 mM of tryptamine. After 6 days, 200 uL supernatant was filtered through a 0.2 pm filter membrane suitable for aquaeus solutions such as the AcroPrep™ Advance, 350 uL, 0.2 micron Supor® membrane for media/water. Next, 20 uL of 250 mg/L caffeine was added to each sample as internal standard before analysis on the LC-MS. 
     The sample caffeine mixtures were analysed on LC-MS to measure secologanin tetrahydroalstonine concentrations. 
     Results 
     Yeast strains expressing CRRC-SGD, RRRC-SGD, RCRC-SGD, CCRC-SGD, CRRR-SGD, CCRR-SGD, RCRR-SGD, and RRRR-SGD were able to produce tetrahydroalstonine ( FIG. 9 ). All functional SGD variants have RseSGD domain 3. All SGD variants with CroSGD domain 3 were not able to produce tetrahydroalstonine. The identity of domain 1 and 2 has low or no effect. Of the functional SGD variants, the four sequences with RseSGD domain 3 and domain 4 (CRRR-SGD, CCRR-SGD, 
     RCRR-SGD, and RRRR-SGD) are able to produce the highest amount of tetrahydroalstonine. CCRR-SGD is the best variant capable of producing more tetrahydroalstonine than the wild type RseSGD (RRRR-SGD) 
     8.2 Production of Tetrahydroalstonine in a Yeast Strain Expressing CCRR_SGD 
     The best SGD variant (CCRR-SGD) were integrated in the MIA-FA strain MIA-FA capable of strain expressing CroG8H+Vmi8HGO-A+NcMLP+NcISY+CroCYB5+CroCPR+CrolO+CroSTR+CroSLS+Cro7DLGT+Cro7DLH+CroLAMT+CroADH2+CroHYS, resulting in the strain MIA-FE: 
     MIA-FE: MIA-FA+CCRR-SGD 
     First, MIA-FE was grown (in triplicates) in 150 uL of YPD overnight to saturation. Then, 10 ul preculture was transferred into 500 uL of synthetic complete (SC) medium with 2% glucose, supplemented with 0.1 mM of secologanin and 1 mM of tryptamine. After 6 days, 200 uL supernatant was filtered through t a 0.2 μm filter membrane suitable for aquaeus solutions such as he AcroPrep™ Advance, 350 uL, 0.2 micron Supor® membrane for media/water. Next, 20 uL of 250 mg/L caffeine was added to each sample as internal standard before analysis on the LC-MS. 
     The sample caffeine mixtures were analysed on LC-MS to measure tetrahydroalstonine concentrations. 
     Results 
     The yeast strain expressing CCRR-SGD was able to produce 13.30 μM (±1.29 μM) tetrahydroalstonine.

     Rescuing the function of other SGD homologs with RseSGD domain 3 and 4 
     Encouraged by the capability of RseSGD domain 3 and 4 to rescue the non-functional CroSGD in yeast three more SGD variants were cloned swapping domain 3 and 4 between RseSGD and UtoSGD (U), GseSGD (G), and RveSGD (V) respectively. Even though swapping domain 3 alone was able to make CroSGD functional swapping both domain 3 and domain 4 gave the largest improvement and therefor this swapping strategy was expanded to other SGD sequences. 
     The sequences of the four domains of UtoSGD, GseSGD and RveSGD were determined from a multiple sequence alignment ( FIG. 12 ). The first residue in domain 1 is always the start methionine and the last residue in domain 4 is always the last residue in the sequence. The remaining first and last residues are defined as the residues aligning with the first and last residues in the four RseSGD domains. Table 8 summarizes the four domains of RseSGD, CroSGD, UtoSGD, GseSGD, and RveSGD.

     Three domain-swap SGD variants and the three wild type SGDs were cloned with USER fusion. The plasmids were transformed into a MIA-FA strain capable of expressing CroG8H+Vmi8HGO-A+NcMLP+NcISY+CroCYB5+CroCPR+CrolO+CroSTR+CroSLS+Cro7DLGT+Cro7DLH+CroLAMT+CroADH2+CroHYS, resulting in strains MIA-FD-17 to MIA-FD-22 (table 9). The MIA-FA strain is capable of synthesizing strictosidine when fed tryptamine and secologanin, or other precursors in the secologanin biosynthetic pathway from geraniol, and is also capable of converting strictosidine aclycone to tetrahydroalstonine if a functional SGD capable of converting strictosidine to strictosidine aglycone is coexpressed

     First, all six strains plus two control strains (MIA-FD-1 and 8) were grown (in triplicates) in 150 uL of synthetic complete without histidine (SC-HIS) overnight to saturation. Then, 10 ul preculture was transferred into 500 uL of SC-HIS medium with 2% glucose, supplemented with 0.1 mM of secologanin and 1 mM of tryptamine. After 6 days, 200 uL supernatant was filtered through a 0.2 pm filter membrane suitable for aquaeus solutions such as the AcroPrep™ Advance, 350 uL, 0.2 micron Supor® membrane for media/water. Next, 20 uL of 250 mg/L caffeine was added to each sample as internal standard before analysis on the LC-MS. 
     The sample caffeine mixtures were analysed on LC-MS to measure tetrahydroalstonine concentrations. 
     As already shown in example 9, swapping in RseSGD domain 3 and 4 rescued the function of the non-functional CroSGD ( FIG. 9 ). Wild type RveSGD is capable of producing tetrahydroalstonine. Swapping in RseSGD domain 3 and 4 improved the tetrahydroalstonine production about seven fold. GseSGD and UtoSGD have lower sequence identity to RseSGD (53.9% and 40.7% respectively) than CroSGD and RveSGD (70.3% and 89.9%). GseSGD can produce tetrahydroalstonine in low concentrations whereas UtoSGD is incapable of tetrahydroalstonine production. Swapping in RseSGD domain 3 and 4 into these two SGDs did not rescue the function of UtoSGD and abolished the low tetrahydroalstonine production of GseSGD. 
     Example 10 
     Minimum Strictosidine Aglycone Production in Yeast 
     Strictosidine aglycone is chemically unstable and was impossible to either purchase or purify to use as a standard for quantification. The minimum strictosidine aglycone produced by the tested SGD homologs was calculated from the measured tetrahydroalstonine produced by the yeast strains and the measured secologanin left in the media. It is possible that not all produced strictosidine aglycone is converted to tetrahydroalstonine, and therefore the true strictosidine aglycone titres might in some cases be higher than the estimated minimum production. 
     Strictosidine Aqlycone Production in μM: 
     Since strictosidine aglycone is converted to tetrahydroalstonine in equimolar amounts, the minimum strictosidine aglycone titre equals the tetrahydroalstonine titre. 
       c(strictosidine aglycone)=c(tetrahydroalstonine) 
     Strictosidine Alycone Yields: 
     The minimum strictosidine algycone yield can be estimated from the strictosidine aglycone titre and the theoretical strictosidine titre. It is assumed that all secologanin taken up by the yeast strain is converted to strictosidine. 
       Strictosidine_aglycone_%=c(strictosidine aglycone)/(c(secologanin supplemented in media)−c(secologanin left after cultivation))
 
     Example 11 
     Production of THA in  Escherichia coli    
     To test if RseSGD or CroSGD could be used for production of strictosidine aglycone and MIAs in prokaryotic microorganisms an expression system was established in the gram-negative bacterium  Escherichia coli  for in vivo conversion of secologanin and tryptamine to strictosidine by CroSTR, conversion of strictosidine to strictosidine aglycone by RseSGD or CroSGD and conversion of strictosidine aglycone to tetrahydroalstonine by CroHYS. Two low-copy plasmids were cloned for co-expression of the three genes from a polycistronic mRNA under control of a medium strength constitutive promoter. The plasmids were based on pCfB3510(p15A_P2BCD2GFP). 
     The two plasmids and an empty plasmid were transformed into the strain DH5-α giving the three strains MIA-ECO-1 to MIA-ECO-3. 
     MIA-ECO-1: D H5-α+p15A-AmpR-CroSTR-CroHYS-CroSGD 
     MIA-ECO-2: DH5-α+p15A-AmpR-CroSTR-CroHYS-RseSGD 
     MIA-ECO-3: DH5-α+p15A-AmpR 
     First, all three strains were grown (in triplicates) in 150 uL of Lysogeny broth (LB) medium with 100 μg/mL ampicillin overnight to saturation. Then, 10 ul preculture was transferred into 500 uL LB medium with 100 μg/mL ampicillin and supplemented with 0.1 mM of secologanin and 1 mM of tryptamine. After 48 hours, 200 uL supernatant was filtered through a 0.2 μm filter membrane suitable for aquaeus solutions such as the AcroPrep™ Advance, 350 uL, 0.2 micron Supor® membrane for media/water. Next, 20 uL of 250 mg/L caffeine was added to each sample as internal standard before analysis on the LC-MS. 
     The sample caffeine mixtures were analysed on LC-MS to measure secologanin, strictosidine, and tetrahydroalstonine concentrations. 
     Results 
     The  E. coli  strain MIA-ECO-2 expressing RseSGD, CroSTR, and CroHYS was able to produce tetrahydroalstonine ( FIG. 11 -B). No strictosidine was detected in the media of the  E. coli  expressing RseSGD. MIA-ECO-1 expressing CroSGD, CroSTR, and CroHYS produced strictosidine ( FIG. 11 -A) but no tetrahydroalstonine, indicating that like in yeast RseSGD is functional and CroSGD is non-functional.
