Construction of Hansenula polymorpha strains with improved thermotolerance
Authors: Ishchuk Olena P. , Voronovsky Andriy Y. , Abbas Charles A. , Sibirny Andriy A.
Published: July 2009

The methylotrophic yeast Hansenula polymorpha has the potential to be used in the process of simultaneous saccharification and fermentation (SSF) of xylan derived xylose at elevated temperatures. To improve parameters of high‐temperature resistance and high‐temperature fermentation of H. polymorpha, strains carrying deletion of acid trehalase gene (ATH1) and overexpressing genes coding for heat‐shock proteins Hsp16p and Hsp104p were constructed. Results indicate that the corresponding recombinant strains have up to 12‐fold increased tolerance to heat‐shock treatment. The deletion of ATH1 gene and constitutive expression of HSP16 and HSP104 resulted in up to 5.8‐fold improvement of ethanol production from xylose at 50°C. Although the maximum ethanol concentration achieved from xylose was 0.9 g L−1, our model H. polymorpha strains with elevated thermotolerance can be further modified by metabolic engineering to construct improved high‐temperature ethanol producers from this pentose.

Published: July 2009

Chinese hamster ovary (CHO) cell lines are widely used for scientific research and biotechnology. A CHO genomic bacterial artificial chromosome (BAC) library was constructed from a mouse dihydrofolate reductase (DHFR) gene‐amplified CHO DR1000L‐4N cell line for genome‐wide analysis of CHO cell lines. The CHO BAC library consisted of 122,281 clones and was expected to cover the entire CHO genome five times. A CHO chromosomal map was constructed by fluorescence in situ hybridization (FISH) imaging using BAC clones as hybridization probes (BAC‐FISH). Thirteen BAC‐FISH marker clones were necessary to identify all the 20 individual chromosomes in a DHFR‐deficient CHO DG44 cell line because of the aneuploidy of the cell line. To determine the genomic structure of the exogenous Dhfr amplicon, a 165‐kb DNA region containing exogenous Dhfr was cloned from the BAC library using high‐density replica (HDR) filters and Southern blot analysis. The nucleotide sequence analysis revealed a novel genomic structure in which the vector sequence containing Dhfr was sandwiched by long inverted sequences of the CHO genome. Biotechnol.

Simultaneous saccharification and co‐fermentation of paper sludge to ethanol by Saccharomyces cerevisiae RWB222—Part I: Kinetic modeling and parameters
Authors: Zhang Jiayi , Shao Xiongjun , Townsend Oliver V. , Lynd Lee R.
Published: July 2009

A kinetic model was developed to predict batch simultaneous saccharification and co‐fermentation (SSCF) of paper sludge by the xylose‐utilizing yeast Saccharomyces cerevisiae RWB222 and the commercial cellulase preparation Spezyme CP. The model accounts for cellulose and xylan enzymatic hydrolysis and competitive uptake of glucose and xylose. Experimental results show that glucan and xylan enzymatic hydrolysis are highly correlated, and that the low concentrations of xylose encountered during SSCF do not have a significant inhibitory effect on enzymatic hydrolysis. Ethanol is found to not only inhibit the specific growth rate, but also to accelerate cell death. Glucose and xylose uptake rates were found to be competitively inhibitory, but this did not have a large impact during SSCF because the sugar concentrations are low. The model was used to evaluate which constants had the greatest impact on ethanol titer for a fixed substrate loading, enzyme loading, and fermentation time. The cellulose adsorption capacity and cellulose hydrolysis rate constants were found to have the greatest impact among enzymatic hydrolysis related constants, and ethanol yield and maximum ethanol tolerance had the greatest impact among fermentation related constants.

Biosynthesis of 2‐Hydroxy and iso‐Even Fatty Acids is Connected to Sphingolipid Formation in Myxobacteria
Authors: Ring Michael W. , Schwär Gertrud , Bode Helge B.
Published: July 2009

2‐Hydroxy fatty acids can be found in several different organisms, including bacteria. In this study, we have studied the biosynthesis of 2‐hydroxy fatty acids in the myxobacteria Myxococcus xanthus and Stigmatella aurantiaca, resulting in the identification of a family of stereospecific fatty acid α‐hydroxylases. Although the stereospecificities of the hydroxylases differ between these two species, they share a common function in supporting fatty acid α‐oxidation; that is, the oxidative shortening of fatty acids. Whereas in S. aurantiaca this process takes place during normal vegetative growth, in M. xanthus it takes place only under developmental conditions. We were also able to identify serine palmitoyltransferase encoding genes involved in sphingolipid biosynthesis as well as sphingolipids themselves in both types of myxobacteria, and were able to show that the α‐hydroxylation reaction is in fact dependent on the presence of fatty acids bound to sphingolipids.
STD‐NMR Studies Suggest that Two Acceptor Substrates for GlfT2, a Bifunctional Galactofuranosyltransferase Required for the Biosynthesis of Mycobacterium tuberculosis Arabinogalactan, Compete for the Same Binding Site
Authors: Szczepina Monica G. , Zheng Ruixiang Blake , Completo Gladys C. , Lowary Todd L. , Pinto B. Mario
Published: July 2009

The mycobacterial cell wall is a complex architecture, which has, as its major structural component, a lipidated polysaccharide covalently bound to peptidoglycan. This structure, termed the mycolyl–arabinogalactan–peptidoglycan complex, possesses a core galactan moiety composed of approximately 30 galactofuranosyl (Galf) resides attached via alternating β‐(1→6) and β‐(1→5) linkages. Recent studies have shown that the entire galactan is synthesized by the action of only two bifunctional galactofuranosyltransferases, GlfT1 and GlfT2. We report here saturation‐transfer difference (STD) NMR spectroscopy studies with GlfT2 using two trisaccharide acceptor substrates, β‐D‐Galf‐(1→6)‐β‐D‐Galf‐(1→5)‐β‐D‐Galf‐O(CH2)7CH3 (2) and β‐D‐Galf‐(1→5)‐β‐D‐Galf‐(1→6)‐β‐D‐Galf‐O(CH2)7CH3 (3), as well as the donor substrate for the enzyme, UDP‐Galf. Competition STD‐NMR titration experiments and saturation transfer double difference (STDD) experiments with 2 and 3 were undertaken to explore the bifunctionality of this enzyme, in particular to answer whether one or two active sites are responsible for the formation of both β‐(1→5)‐ and β‐(1→6)‐Galf linkages. It was demonstrated that 2 and 3 bind competitively at the same site; this suggests that GlfT2 has one active site pocket capable of catalyzing both β‐(1→5) and β‐(1→6) galactofuranosyl transfer reactions. The addition of UDP‐Galf to GlfT2 in the presence of either 2 or 3 generated a tetrasaccharide product; this indicates that the enzyme was catalytically active under the conditions at which the STD‐NMR experiments were carried out.
Influence of the Nucleophile on the Candida antarctica Lipase B‐Catalysed Resolution of a Chiral Acyl Donor
Authors: García‐Urdiales Eduardo , Ríos‐Lombardía Nicolás , Mangas‐Sánchez Juan , Gotor‐Fernández Vicente , Gotor Vicente
Published: July 2009

The resolution of methyl (±)‐3‐hydroxypentanoate catalysed by Candida antarctica lipase B has been performed by using ammonia and benzyl amine as nucleophiles. In all cases, the lipase reacts faster with the R enantiomer of the ester, but when benzyl amine is used, the enantiomeric ratio is approximately three times as high as that measured for ammonia. The analysis of the molecular dynamics simulations carried out over the corresponding deacylation transition state analogues indicated specular binding modes between enantiomers that vary greatly upon the nucleophile used. For the case of ammonia, an intramolecular hydrogen bond between the β‐hydroxyl group and the protons of the nucleophile is established. However, the presence of the substituent in benzyl amine disrupts this interaction. Instead, the acyl chain binds to a more restrictive area of the protein where the higher number of contacts established with the side chains of Thr40, Gln157 and Ile189 have been identified as the reason for the higher enantioselectivity observed in the aminolysis reaction.
Mechanisms in the Reaction of Palladium(II)–π‐Allyl Complexes with Aryl Halides: Evidence for NHC Exchange Between Two Palladium Complexes
Authors: Normand Adrien T. , Nechaev Mikhail S. , Cavell Kingsley J.
Published: July 2009

A detailed experimental and DFT study (PBE level) of the reaction of [Pd(η3‐C3H5)(tmiy)(PR3)]BF4 (tmiy=tetramethylimidazolin‐2‐ylidene, PR3=phosphane), precursors to monoligated Pd0 species, with aryl electrophiles yielding 2‐arylimidazolium salt is reported. Experiments establish that an autocatalytic ligand transfer mechanism is preferred over PdIV and σ‐bond metathesis pathways, and that transmetalation is the rate‐determining step. Calculations indicate that the key step involves the concerted exchange of NHC and iodo ligands between two different PdII complexes. This is corroborated by experimental results showing the slower reaction of complexes containing the bulkier dipdmiy (dipdmiy = diisopropyldimethylimidazolin‐2‐ylidene).
A Cascade FRET‐Mediated Ratiometric Sensor for Cu2+Ions Based on Dual Fluorescent Ligand‐Coated Polymer Nanoparticles
Authors: Frigoli Michel , Ouadahi Karima , Larpent Chantal
Published: July 2009

Core‐shell type dual fluorescent nanoparticles (NPs) in the 16 nm diameter range with a selective ligand (cyclam) attached to the surface and two fluorophores—9,10‐diphenyl‐anthracene (donor, D) and pyrromethene PM 567 (acceptor, A)—embedded within the polymer core were synthesized and their fluorescent and copper‐sensing properties were studied and compared to single D‐doped and A‐doped NPs. The acceptor (A) and donor (D) dyes were chosen to allow two sequential Förster resonance energy transfer (FRET) processes from D to A and from the encapsulated dyes to copper complexes that form at the surface and act as quenchers. NPs with different D/A loads were readily obtained by two consecutive entrapments of the dyes. Dual NPs present tunable fluorescence emission that is dependent on the doping ratio. FRET from D to A results in sensitized emission from A upon excitation of D, with FRET efficiencies reaching 80 % at high acceptor loads. A 9‐fold amplification of the signal of A is observed at high D‐to‐A ratios. Single‐ and dual‐dye‐doped NPs were used to detect the presence of cupric ions in water by using the quenching of fluorescence as a transduction signal. In accordance with the spectral overlaps and the values of the critical distance (R0) of D– and A–copper complex pairs, the acceptor is much more sensitive than the donor. In dual fluorescent NPs, the sensitized emission of A is efficiently attenuated whereas the remaining emission of D is much less affected, allowing the detection of copper in a ratiometric manner upon excitation at a single (D) wavelength. Dual‐dye‐doped NPs with the highest acceptor loads (23 A‐per‐NP) were found to be the most sensitive for the detection of copper over a wide range of concentrations (20 nM to 8.5 μM). Owing to its great convenience and modularity, the cascade FRET strategy based on dual fluorescent NPs holds great promise for the design of various sensing nanodevices.
Oxyma: An Efficient Additive for Peptide Synthesis to Replace the Benzotriazole‐Based HOBt and HOAt with a Lower Risk of Explosion[1]
Authors: Subirós‐Funosas Ramon , Prohens Rafel , Barbas Rafael , El‐Faham Ayman , Albericio Fernando
Published: July 2009

Oxyma [ethyl 2‐cyano‐2‐(hydroxyimino)acetate] has been tested as an additive for use in the carbodiimide approach for formation of peptide bonds. Its performance in relation to those of HOBt and HOAt, which have recently been reported to exhibit explosive properties, is reported. Oxyma displayed a remarkable capacity to inhibit racemization, together with impressive coupling efficiency in both automated and manual synthesis, superior to those of HOBt and at least comparable to those of HOAt, and surpassing the latter coupling agent in the more demanding peptide models. Stability assays showed that there was no risk of capping the resin under standard coupling conditions. Finally, calorimetry assays (DSC and ARC) showed decomposition profiles for benzotriazole‐based additives that were consistent with their reported explosivities and suggested a lower risk of explosion in the case of Oxyma.
Stereospecific Synthesis of β3‐Amino Acid Derivatives from Propargylic Alcohols: Efficient Solution‐Phase Synthesis of Oligopeptides without Coupling Agents
Authors: Temperini Andrea , Terlizzi Raffaella , Testaferri Lorenzo , Tiecco Marcello
Published: July 2009

A stereospecific synthesis of β3‐amino acids has been accomplished starting from readily available and enantioenriched propargylic alcohols. This conversion can be effected in only three steps by selenium‐mediated organic transformations of the carbon–carbon triple bond. This method is especially attractive because the reactive Se‐phenyl selenocarboxylate intermediates can be trapped with the amine functionality of an amino acid derivative. Through this strategy a chain elongation at the N‐terminus has been effected. The N‐deprotection and repetition of the homologation with other Se‐phenyl selenocarboxylate intermediates produced β‐ and mixed α/β‐oligopeptides without the use of coupling agents.
From Polymer to Size‐Defined Oligomers: A Step Economy Process for the Efficient and Stereocontrolled Construction of Chondroitin Oligosaccharides and Biotinylated Conjugates Thereof: Part 1
Authors: Vibert Aude , Lopin‐Bon Chrystel , Jacquinet Jean‐Claude
Published: July 2009

Controlled acid hydrolysis of polymeric chondroitin sulfate of bovine origin afforded in good yield a basic disaccharide fragment that was used for the first time as a starting material for the expeditious preparation of a set of building blocks that in turn act as versatile synthons for the efficient and stereocontrolled construction of a collection of size‐defined chondroitin oligomers (from di‐ to octasaccharides). This step economy process allows their preparation as reducing species, fitted with a fluorophore, or as biotinylated conjugates; all useful tools for the preparation of microarrays, or as probes for the study of the biosynthesis of chondroitin sulfate.
Diiron Proton Reduction Catalysts Possessing Electron‐Rich and Electron‐Poor Naphthalene‐1,8‐dithiolate Ligands
Authors: Wright Robert J. , Lim Christopher , Tilley T. Don
Published: July 2009

The diiron complexes [Fe2(CO)6(1,8‐S2‐2,4,5,7‐Cl4C10H2)] (3), [Fe2(CO)6(1,8‐S2C10H6)] (4), and [Fe2(CO)6(1,8‐S2‐2,7‐tBu2C10H4)] (5) were synthesized in moderate yield from naphthalene‐1,8‐dithiols and [Fe3(CO)12]. They were characterized by IR, 1H and 13C NMR spectroscopy and 3 and 4 were characterized by X‐ray crystallography. They contain a butterfly Fe2S2 core with Fe–Fe distances of 2.529(1) (3) and 2.506(1) Å (4). Cyclic voltammetry (CH2Cl2/nBu4PF6) revealed two one‐electron reductions, at potentials more positive than those for the related [Fe2(CO)6(S(CH2)3S)] (1), and one one‐electron oxidation. The first reduction of the electron poor 3 (−1.60 V vs Fc/Fc+) is 240 mV more positive than the first reduction of the electron rich 5 (−1.84 V). Electrochemical studies revealed that 3–5 facilitate the proton reduction of p‐toluenesulfonic acid. The rates of catalysis, with a 95 % confidence limit, are 2.4±0.8 (1), 5.2±0.8 (3), 3.1±1.1 (4), 2.9±0.6 (5), and 4.5±0.2 h−1 for the related [Fe2(CO)6(1,2‐S2C6H4)]. The rates were determined by bulk electrolysis at −1.70 V (Fc/Fc+), which correspond to an overpotential of 1.05 V for p‐toluenesulfonic acid.
