DETAILED DESCRIPTION
Unless otherwise defined herein, scientific and technical terms used in connection with the present invention shall have the meanings that are commonly understood by those of ordinary skill in the art. Further, unless otherwise required by context, singular terms shall include the plural and plural terms shall include the singular. Generally, nomenclatures used in connection with, and techniques of, biochemistry, enzymology, molecular and cellular biology, microbiology, genetics and protein and nucleic acid chemistry and hybridization described herein are those well known and commonly used in the art.
The methods and techniques of the present invention are generally performed according to conventional methods well known in the art and as described in various general and more specific references that are cited and discussed throughout the present specification unless otherwise indicated. See, e.g., Sambrook et al., Molecular Cloning: A Laboratory Manual, 2d ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y. (1989); Ausubel et al., Current Protocols in Molecular Biology, Greene Publishing Associates (1992, and Supplements to 2002); Harlow and Lane, Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y.

All publications, patents and other references mentioned herein are hereby incorporated by reference in their entireties.
The following terms, unless otherwise indicated, shall be understood to have the following meanings:
The term “polynucleotide” or “nucleic acid molecule” refers to a polymeric form of nucleotides of at least 10 bases in length. The term includes DNA molecules (e.g., cDNA or genomic or synthetic DNA) and RNA molecules (e.g., mRNA or synthetic RNA), as well as analogs of DNA or RNA containing non-natural nucleotide analogs, non-native internucleoside bonds, or both. The nucleic acid can be in any topological conformation. For instance, the nucleic acid can be single-stranded, double-stranded, triple-stranded, quadruplexed, partially double-stranded, branched, hairpinned, circular, or in a padlocked conformation.
Unless otherwise indicated, and as an example for all sequences described herein under the general format “SEQ ID NO:”, “nucleic acid comprising SEQ ID NO:1” refers to a nucleic acid, at least a portion of which has either (i) the sequence of SEQ ID NO:1, or (ii) a sequence complementary to SEQ ID NO:1. The choice between the two is dictated by the context. For instance, if the nucleic acid is used as a probe, the choice between the two is dictated by the requirement that the probe be complementary to the desired target.
An “isolated” RNA, DNA or a mixed polymer is one which is substantially separated from other cellular components that naturally accompany the native polynucleotide in its natural host cell, e.g., ribosomes, polymerases and genomic sequences with which it is naturally associated.
As used herein, an “isolated” organic molecule (e.g., an alkane) is one which is substantially separated from the cellular components (membrane lipids, chromosomes, proteins) of the host cell from which it originated, or from the medium in which the host cell was cultured. The term does not require that the biomolecule has been separated from all other chemicals, although certain isolated biomolecules may be purified to near homogeneity.
The term “recombinant” refers to a biomolecule, e.g., a gene or protein, that (1) has been removed from its naturally occurring environment, (2) is not associated with all or a portion of a polynucleotide in which the gene is found in nature, (3) is operatively linked to a polynucleotide which it is not linked to in nature, or (4) does not occur in nature. The term “recombinant” can be used in reference to cloned DNA isolates, chemically synthesized polynucleotide analogs, or polynucleotide analogs that are biologically synthesized by heterologous systems, as well as proteins and/or mRNAs encoded by such nucleic acids.
As used herein, an endogenous nucleic acid sequence in the genome of an organism (or the encoded protein product of that sequence) is deemed “recombinant” herein if a heterologous sequence is placed adjacent to the endogenous nucleic acid sequence, such that the expression of this endogenous nucleic acid sequence is altered. In this context, a heterologous sequence is a sequence that is not naturally adjacent to the endogenous nucleic acid sequence, whether or not the heterologous sequence is itself endogenous (originating from the same host cell or progeny thereof) or exogenous (originating from a different host cell or progeny thereof). By way of example, a promoter sequence can be substituted (e.g., by homologous recombination) for the native promoter of a gene in the genome of a host cell, such that this gene has an altered expression pattern. This gene would now become “recombinant” because it is separated from at least some of the sequences that naturally flank it.
A nucleic acid is also considered “recombinant” if it contains any modifications that do not naturally occur to the corresponding nucleic acid in a genome. For instance, an endogenous coding sequence is considered “recombinant” if it contains an insertion, deletion or a point mutation introduced artificially, e.g., by human intervention. A “recombinant nucleic acid” also includes a nucleic acid integrated into a host cell chromosome at a heterologous site and a nucleic acid construct present as an episome.
As used herein, the phrase “degenerate variant” of a reference nucleic acid sequence encompasses nucleic acid sequences that can be translated, according to the standard genetic code, to provide an amino acid sequence identical to that translated from the reference nucleic acid sequence. The term “degenerate oligonucleotide” or “degenerate primer” is used to signify an oligonucleotide capable of hybridizing with target nucleic acid sequences that are not necessarily identical in sequence but that are homologous to one another within one or more particular segments.
The term “percent sequence identity” or “identical” in the context of nucleic acid sequences refers to the residues in the two sequences which are the same when aligned for maximum correspondence. The length of sequence identity comparison may be over a stretch of at least about nine nucleotides, usually at least about 20 nucleotides, more usually at least about 24 nucleotides, typically at least about 28 nucleotides, more typically at least about 32 nucleotides, and preferably at least about 36 or more nucleotides. There are a number of different algorithms known in the art which can be used to measure nucleotide sequence identity. For instance, polynucleotide sequences can be compared using FASTA, Gap or Bestfit, which are programs in Wisconsin Package Version 10.0, Genetics Computer Group (GCG), Madison, Wis. FASTA provides alignments and percent sequence identity of the regions of the best overlap between the query and search sequences. Pearson, Methods Enzymol. 183:63-98 (1990) (hereby incorporated by reference in its entirety). For instance, percent sequence identity between nucleic acid sequences can be determined using FASTA with its default parameters (a word size of 6 and the NOPAM factor for the scoring matrix) or using Gap with its default parameters as provided in GCG Version 6.1, herein incorporated by reference. Alternatively, sequences can be compared using the computer program, BLAST (Altschul et al., J. Mol. Biol. 215:403-410 (1990); Gish and States, Nature Genet. 3:266-272 (1993); Madden et al., Meth. Enzymol. 266:131-141 (1996); Altschul et al., Nucleic Acids Res. 25:3389-3402 (1997); Zhang and Madden, Genome Res. 7:649-656 (1997)), especially blastp or tblastn (Altschul et al., Nucleic Acids Res. 25:3389-3402 (1997)).
The term “substantial homology” or “substantial similarity,” when referring to a nucleic acid or fragment thereof, indicates that, when optimally aligned with appropriate nucleotide insertions or deletions with another nucleic acid (or its complementary strand), there is nucleotide sequence identity in at least about 76%, 80%, 85%, preferably at least about 90%, and more preferably at least about 95%, 96%, 97%, 98% or 99% of the nucleotide bases, as measured by any well-known algorithm of sequence identity, such as FASTA, BLAST or Gap, as discussed above.
Alternatively, substantial homology or similarity exists when a nucleic acid or fragment thereof hybridizes to another nucleic acid, to a strand of another nucleic acid, or to the complementary strand thereof, under stringent hybridization conditions. “Stringent hybridization conditions” and “stringent wash conditions” in the context of nucleic acid hybridization experiments depend upon a number of different physical parameters. Nucleic acid hybridization will be affected by such conditions as salt concentration, temperature, solvents, the base composition of the hybridizing species, length of the complementary regions, and the number of nucleotide base mismatches between the hybridizing nucleic acids, as will be readily appreciated by those skilled in the art. One having ordinary skill in the art knows how to vary these parameters to achieve a particular stringency of hybridization.
In general, “stringent hybridization” is performed at about 25° C. below the thermal melting point (Tm) for the specific DNA hybrid under a particular set of conditions. “Stringent washing” is performed at temperatures about 5° C. lower than the Tm for the specific DNA hybrid under a particular set of conditions. The Tm is the temperature at which 50% of the target sequence hybridizes to a perfectly matched probe. See Sambrook et al., Molecular Cloning: A Laboratory Manual, 2d ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y. (1989), page 9.51, hereby incorporated by reference. For purposes herein, “stringent conditions” are defined for solution phase hybridization as aqueous hybridization (i.e., free of formamide) in 6×SSC (where 20×SSC contains 3.0 M NaCl and 0.3 M sodium citrate), 1% SDS at 65° C. for 8-12 hours, followed by two washes in 0.2×SSC, 0.1% SDS at 65° C. for 20 minutes. It will be appreciated by the skilled worker that hybridization at 65° C. will occur at different rates depending on a number of factors including the length and percent identity of the sequences which are hybridizing.
The nucleic acids (also referred to as polynucleotides) of this present invention may include both sense and antisense strands of RNA, cDNA, genomic DNA, and synthetic forms and mixed polymers of the above. They may be modified chemically or biochemically or may contain non-natural or derivatized nucleotide bases, as will be readily appreciated by those of skill in the art. Such modifications include, for example, labels, methylation, substitution of one or more of the naturally occurring nucleotides with an analog, internucleotide modifications such as uncharged linkages (e.g., methyl phosphonates, phosphotriesters, phosphoramidates, carbamates, etc.), charged linkages (e.g., phosphorothioates, phosphorodithioates, etc.), pendent moieties (e.g., polypeptides), intercalators (e.g., acridine, psoralen, etc.), chelators, alkylators, and modified linkages (e.g., alpha anomeric nucleic acids, etc.) Also included are synthetic molecules that mimic polynucleotides in their ability to bind to a designated sequence via hydrogen bonding and other chemical interactions. Such molecules are known in the art and include, for example, those in which peptide linkages substitute for phosphate linkages in the backbone of the molecule. Other modifications can include, for example, analogs in which the ribose ring contains a bridging moiety or other structure such as the modifications found in “locked” nucleic acids.
The term “mutated” when applied to nucleic acid sequences means that nucleotides in a nucleic acid sequence may be inserted, deleted or changed compared to a reference nucleic acid sequence. A single alteration may be made at a locus (a point mutation) or multiple nucleotides may be inserted, deleted or changed at a single locus. In addition, one or more alterations may be made at any number of loci within a nucleic acid sequence. A nucleic acid sequence may be mutated by any method known in the art including but not limited to mutagenesis techniques such as “error-prone PCR” (a process for performing PCR under conditions where the copying fidelity of the DNA polymerase is low, such that a high rate of point mutations is obtained along the entire length of the PCR product; see, e.g., Leung et al., Technique, 1:11-15 (1989) and Caldwell and Joyce, PCR Methods Applic. 2:28-33 (1992)); and “oligonucleotide-directed mutagenesis” (a process which enables the generation of site-specific mutations in any cloned DNA segment of interest; see, e.g., Reidhaar-Olson and Sauer, Science 241:53-57 (1988)).
The term “attenuate” as used herein generally refers to a functional deletion, including a mutation, partial or complete deletion, insertion, or other variation made to a gene sequence or a sequence controlling the transcription of a gene sequence, which reduces or inhibits production of the gene product, or renders the gene product non-functional. In some instances a functional deletion is described as a knockout mutation. Attenuation also includes amino acid sequence changes by altering the nucleic acid sequence, placing the gene under the control of a less active promoter, down-regulation, expressing interfering RNA, ribozymes or antisense sequences that target the gene of interest, or through any other technique known in the art. In one example, the sensitivity of a particular enzyme to feedback inhibition or inhibition caused by a composition that is not a product or a reactant (non-pathway specific feedback) is lessened such that the enzyme activity is not impacted by the presence of a compound. In other instances, an enzyme that has been altered to be less active can be referred to as attenuated.
Deletion: The removal of one or more nucleotides from a nucleic acid molecule or one or more amino acids from a protein, the regions on either side being joined together.
Knock-out: A gene whose level of expression or activity has been reduced to zero. In some examples, a gene is knocked-out via deletion of some or all of its coding sequence. In other examples, a gene is knocked-out via introduction of one or more nucleotides into its open reading frame, which results in translation of a non-sense or otherwise non-functional protein product.
The term “vector” as used herein is intended to refer to a nucleic acid molecule capable of transporting another nucleic acid to which it has been linked. One type of vector is a “plasmid,” which generally refers to a circular double stranded DNA loop into which additional DNA segments may be ligated, but also includes linear double-stranded molecules such as those resulting from amplification by the polymerase chain reaction (PCR) or from treatment of a circular plasmid with a restriction enzyme. Other vectors include cosmids, bacterial artificial chromosomes (BAC) and yeast artificial chromosomes (YAC). Another type of vector is a viral vector, wherein additional DNA segments may be ligated into the viral genome (discussed in more detail below). Certain vectors are capable of autonomous replication in a host cell into which they are introduced (e.g., vectors having an origin of replication which functions in the host cell). Other vectors can be integrated into the genome of a host cell upon introduction into the host cell, and are thereby replicated along with the host genome. Moreover, certain preferred vectors are capable of directing the expression of genes to which they are operatively linked. Such vectors are referred to herein as “recombinant expression vectors” (or simply “expression vectors”).
“Operatively linked” or “operably linked” expression control sequences refers to a linkage in which the expression control sequence is contiguous with the gene of interest to control the gene of interest, as well as expression control sequences that act in trans or at a distance to control the gene of interest.
The term “expression control sequence” as used herein refers to polynucleotide sequences which are necessary to affect the expression of coding sequences to which they are operatively linked. Expression control sequences are sequences which control the transcription, post-transcriptional events and translation of nucleic acid sequences. Expression control sequences include appropriate transcription initiation, termination, promoter and enhancer sequences; efficient RNA processing signals such as splicing and polyadenylation signals; sequences that stabilize cytoplasmic mRNA; sequences that enhance translation efficiency (e.g., ribosome binding sites); sequences that enhance protein stability; and when desired, sequences that enhance protein secretion. The nature of such control sequences differs depending upon the host organism; in prokaryotes, such control sequences generally include promoter, ribosomal binding site, and transcription termination sequence. The term “control sequences” is intended to include, at a minimum, all components whose presence is essential for expression, and can also include additional components whose presence is advantageous, for example, leader sequences and fusion partner sequences.
The term “recombinant host cell” (or simply “host cell”), as used herein, is intended to refer to a cell into which a recombinant vector has been introduced. It should be understood that such terms are intended to refer not only to the particular subject cell but to the progeny of such a cell. Because certain modifications may occur in succeeding generations due to either mutation or environmental influences, such progeny may not, in fact, be identical to the parent cell, but are still included within the scope of the term “host cell” as used herein. A recombinant host cell may be an isolated cell or cell line grown in culture or may be a cell which resides in a living tissue or organism.
The term “peptide” as used herein refers to a short polypeptide, e.g., one that is typically less than about 50 amino acids long and more typically less than about 30 amino acids long. The term as used herein encompasses analogs and mimetics that mimic structural and thus biological function.
The term “polypeptide” encompasses both naturally-occurring and non-naturally-occurring proteins, and fragments, mutants, derivatives and analogs thereof. A polypeptide may be monomeric or polymeric. Further, a polypeptide may comprise a number of different domains each of which has one or more distinct activities.
The term “isolated protein” or “isolated polypeptide” is a protein or polypeptide that by virtue of its origin or source of derivation (1) is not associated with naturally associated components that accompany it in its native state, (2) exists in a purity not found in nature, where purity can be adjudged with respect to the presence of other cellular material (e.g., is free of other proteins from the same species) (3) is expressed by a cell from a different species, or (4) does not occur in nature (e.g., it is a fragment of a polypeptide found in nature or it includes amino acid analogs or derivatives not found in nature or linkages other than standard peptide bonds). Thus, a polypeptide that is chemically synthesized or synthesized in a cellular system different from the cell from which it naturally originates will be “isolated” from its naturally associated components. A polypeptide or protein may also be rendered substantially free of naturally associated components by isolation, using protein purification techniques well known in the art. As thus defined, “isolated” does not necessarily require that the protein, polypeptide, peptide or oligopeptide so described has been physically removed from its native environment.
The term “polypeptide fragment” as used herein refers to a polypeptide that has a deletion, e.g., an amino-terminal and/or carboxy-terminal deletion compared to a full-length polypeptide. In a preferred embodiment, the polypeptide fragment is a contiguous sequence in which the amino acid sequence of the fragment is identical to the corresponding positions in the naturally-occurring sequence. Fragments typically are at least 5, 6, 7, 8, 9 or 10 amino acids long, preferably at least 12, 14, 16 or 18 amino acids long, more preferably at least 20 amino acids long, more preferably at least 25, 30, 35, 40 or 45, amino acids, even more preferably at least 50 or 60 amino acids long, and even more preferably at least 70 amino acids long.
A “modified derivative” refers to polypeptides or fragments thereof that are substantially homologous in primary structural sequence but which include, e.g., in vivo or in vitro chemical and biochemical modifications or which incorporate amino acids that are not found in the native polypeptide. Such modifications include, for example, acetylation, carboxylation, phosphorylation, glycosylation, ubiquitination, labeling, e.g., with radionuclides, and various enzymatic modifications, as will be readily appreciated by those skilled in the art. A variety of methods for labeling polypeptides and of substituents or labels useful for such purposes are well known in the art, and include radioactive isotopes such as 125I, 32P, 35S, and 3H, ligands which bind to labeled antiligands (e.g., antibodies), fluorophores, chemiluminescent agents, enzymes, and antiligands which can serve as specific binding pair members for a labeled ligand. The choice of label depends on the sensitivity required, ease of conjugation with the primer, stability requirements, and available instrumentation. Methods for labeling polypeptides are well known in the art. See, e.g., Ausubel et al., Current Protocols in Molecular Biology, Greene Publishing Associates (1992, and Supplements to 2002) (hereby incorporated by reference).
The term “fusion protein” refers to a polypeptide comprising a polypeptide or fragment coupled to heterologous amino acid sequences. Fusion proteins are useful because they can be constructed to contain two or more desired functional elements from two or more different proteins. A fusion protein comprises at least 10 contiguous amino acids from a polypeptide of interest, more preferably at least 20 or 30 amino acids, even more preferably at least 40, 50 or 60 amino acids, yet more preferably at least 75, 100 or 125 amino acids. Fusions that include the entirety of the proteins of the present invention have particular utility. The heterologous polypeptide included within the fusion protein of the present invention is at least 6 amino acids in length, often at least 8 amino acids in length, and usefully at least 15, 20, and 25 amino acids in length. Fusions that include larger polypeptides, such as an IgG Fc region, and even entire proteins, such as the green fluorescent protein (“GFP”) chromophore-containing proteins, have particular utility. Fusion proteins can be produced recombinantly by constructing a nucleic acid sequence which encodes the polypeptide or a fragment thereof in frame with a nucleic acid sequence encoding a different protein or peptide and then expressing the fusion protein. Alternatively, a fusion protein can be produced chemically by crosslinking the polypeptide or a fragment thereof to another protein.
The term “non-peptide analog” refers to a compound with properties that are analogous to those of a reference polypeptide. A non-peptide compound may also be termed a “peptide mimetic” or a “peptidomimetic.” See, e.g., Jones, Amino Acid and Peptide Synthesis, Oxford University Press (1992); Jung, Combinatorial Peptide and Nonpeptide Libraries: A Handbook, John Wiley (1997); Bodanszky et al., Peptide Chemistry—A Practical Textbook, Springer Verlag (1993); Synthetic Peptides: A Users Guide, (Grant, ed., W. H. Freeman and Co., 1992); Evans et al., J. Med. Chem. 30:1229 (1987); Fauchere, J. Adv. Drug Res. 15:29 (1986); Veber and Freidinger, Trends Neurosci., 8:392-396 (1985); and references sited in each of the above, which are incorporated herein by reference. Such compounds are often developed with the aid of computerized molecular modeling. Peptide mimetics that are structurally similar to useful peptides of the present invention may be used to produce an equivalent effect and are therefore envisioned to be part of the present invention.
A “polypeptide mutant” or “mutein” refers to a polypeptide whose sequence contains an insertion, duplication, deletion, rearrangement or substitution of one or more amino acids compared to the amino acid sequence of a native or wild-type protein. A mutein may have one or more amino acid point substitutions, in which a single amino acid at a position has been changed to another amino acid, one or more insertions and/or deletions, in which one or more amino acids are inserted or deleted, respectively, in the sequence of the naturally-occurring protein, and/or truncations of the amino acid sequence at either or both the amino or carboxy termini. A mutein may have the same but preferably has a different biological activity compared to the naturally-occurring protein.
A mutein has at least 85% overall sequence homology to its wild-type counterpart. Even more preferred are muteins having at least 90% overall sequence homology to the wild-type protein.
In an even more preferred embodiment, a mutein exhibits at least 95% sequence identity, even more preferably 98%, even more preferably 99% and even more preferably 99.9% overall sequence identity.
Sequence homology may be measured by any common sequence analysis algorithm, such as Gap or Bestfit.
Amino acid substitutions can include those which: (1) reduce susceptibility to proteolysis, (2) reduce susceptibility to oxidation, (3) alter binding affinity for forming protein complexes, (4) alter binding affinity or enzymatic activity, and (5) confer or modify other physicochemical or functional properties of such analogs.
As used herein, the twenty conventional amino acids and their abbreviations follow conventional usage. See Immunology—A Synthesis (Golub and Gren eds., Sinauer Associates, Sunderland, Mass., 2nd ed. 1991), which is incorporated herein by reference. Stereoisomers (e.g., D-amino acids) of the twenty conventional amino acids, unnatural amino acids such as α-, α-disubstituted amino acids, N-alkyl amino acids, and other unconventional amino acids may also be suitable components for polypeptides of the present invention. Examples of unconventional amino acids include: 4-hydroxyproline, γ-carboxyglutamate, ε-N,N,N-trimethyllysine, ε-N-acetyllysine, O-phosphoserine, N-acetylserine, N-formylmethionine, 3-methylhistidine, 5-hydroxylysine, N-methylarginine, and other similar amino acids and imino acids (e.g., 4-hydroxyproline). In the polypeptide notation used herein, the left-hand end corresponds to the amino terminal end and the right-hand end corresponds to the carboxy-terminal end, in accordance with standard usage and convention.
A protein has “homology” or is “homologous” to a second protein if the nucleic acid sequence that encodes the protein has a similar sequence to the nucleic acid sequence that encodes the second protein. Alternatively, a protein has homology to a second protein if the two proteins have “similar” amino acid sequences. (Thus, the term “homologous proteins” is defined to mean that the two proteins have similar amino acid sequences.) As used herein, homology between two regions of amino acid sequence (especially with respect to predicted structural similarities) is interpreted as implying similarity in function.
When “homologous” is used in reference to proteins or peptides, it is recognized that residue positions that are not identical often differ by conservative amino acid substitutions. A “conservative amino acid substitution” is one in which an amino acid residue is substituted by another amino acid residue having a side chain (R group) with similar chemical properties (e.g., charge or hydrophobicity). In general, a conservative amino acid substitution will not substantially change the functional properties of a protein. In cases where two or more amino acid sequences differ from each other by conservative substitutions, the percent sequence identity or degree of homology may be adjusted upwards to correct for the conservative nature of the substitution. Means for making this adjustment are well known to those of skill in the art. See, e.g., Pearson, 1994, Methods Mol. Biol. 24:307-31 and 25:365-89 (herein incorporated by reference).
The following six groups each contain amino acids that are conservative substitutions for one another: 1) Serine (S), Threonine (T); 2) Aspartic Acid (D), Glutamic Acid (E); 3) Asparagine (N), Glutamine (Q); 4) Arginine (R), Lysine (K); 5) Isoleucine (I), Leucine (L), Methionine (M), Alanine (A), Valine (V), and 6) Phenylalanine (F), Tyrosine (Y), Tryptophan (W).
Sequence homology for polypeptides, which is also referred to as percent sequence identity, is typically measured using sequence analysis software. See, e.g., the Sequence Analysis Software Package of the Genetics Computer Group (GCG), University of Wisconsin Biotechnology Center, 910 University Avenue, Madison, Wis. 53705. Protein analysis software matches similar sequences using a measure of homology assigned to various substitutions, deletions and other modifications, including conservative amino acid substitutions. For instance, GCG contains programs such as “Gap” and “Bestfit” which can be used with default parameters to determine sequence homology or sequence identity between closely related polypeptides, such as homologous polypeptides from different species of organisms or between a wild-type protein and a mutein thereof. See, e.g., GCG Version 6.1.
A preferred algorithm when comparing a particular polypeptide sequence to a database containing a large number of sequences from different organisms is the computer program BLAST (Altschul et al., J. Mol. Biol. 215:403-410 (1990); Gish and States, Nature Genet. 3:266-272 (1993); Madden et al., Meth. Enzymol. 266:131-141 (1996); Altschul et al., Nucleic Acids Res. 25:3389-3402 (1997); Zhang and Madden, Genome Res. 7:649-656 (1997)), especially blastp or tblastn (Altschul et al., Nucleic Acids Res. 25:3389-3402 (1997)).
Preferred parameters for BLASTp are: Expectation value: 10 (default); Filter: seg (default); Cost to open a gap: 11 (default); Cost to extend a gap: 1 (default); Max. alignments: 100 (default); Word size: 11 (default); No. of descriptions: 100 (default); Penalty Matrix: BLOWSUM62.
The length of polypeptide sequences compared for homology will generally be at least about 16 amino acid residues, usually at least about 20 residues, more usually at least about 24 residues, typically at least about 28 residues, and preferably more than about 35 residues. When searching a database containing sequences from a large number of different organisms, it is preferable to compare amino acid sequences. Database searching using amino acid sequences can be measured by algorithms other than blastp known in the art. For instance, polypeptide sequences can be compared using FASTA, a program in GCG Version 6.1. FASTA provides alignments and percent sequence identity of the regions of the best overlap between the query and search sequences. Pearson, Methods Enzymol. 183:63-98 (1990) (incorporated by reference herein). For example, percent sequence identity between amino acid sequences can be determined using FASTA with its default parameters (a word size of 2 and the PAM250 scoring matrix), as provided in GCG Version 6.1, herein incorporated by reference.
“Specific binding” refers to the ability of two molecules to bind to each other in preference to binding to other molecules in the environment. Typically, “specific binding” discriminates over adventitious binding in a reaction by at least two-fold, more typically by at least 10-fold, often at least 100-fold. Typically, the affinity or avidity of a specific binding reaction, as quantified by a dissociation constant, is about 10−7 M or stronger (e.g., about 10−8 M, 10−9 M or even stronger).
The term “region” as used herein refers to a physically contiguous portion of the primary structure of a biomolecule. In the case of proteins, a region is defined by a contiguous portion of the amino acid sequence of that protein.
The term “domain” as used herein refers to a structure of a biomolecule that contributes to a known or suspected function of the biomolecule. Domains may be co-extensive with regions or portions thereof; domains may also include distinct, non-contiguous regions of a biomolecule. Examples of protein domains include, but are not limited to, an Ig domain, an extracellular domain, a transmembrane domain, and a cytoplasmic domain.
As used herein, the term “molecule” means any compound, including, but not limited to, a small molecule, peptide, protein, sugar, nucleotide, nucleic acid, lipid, etc., and such a compound can be natural or synthetic.
“Carbon-based Products of Interest” include alcohols such as ethanol, propanol, isopropanol, butanol, fatty alcohols, fatty acid esters, wax esters; hydrocarbons and alkanes such as propane, octane, diesel, Jet Propellant 8 (JP8); polymers such as terephthalate, 1,3-propanediol, 1,4-butanediol, polyols, Polyhydroxyalkanoates (PHA), poly-beta-hydroxybutyrate (PHB), acrylate, adipic acid, ε-caprolactone, isoprene, caprolactam, rubber; commodity chemicals such as lactate, Docosahexaenoic acid (DHA), 3-hydroxypropionate, γ-valerolactone, lysine, serine, aspartate, aspartic acid, sorbitol, ascorbate, ascorbic acid, isopentenol, lanosterol, omega-3 DHA, lycopene, itaconate, 1,3-butadiene, ethylene, propylene, succinate, citrate, citric acid, glutamate, malate, 3-hydroxypropionic acid (HPA), lactic acid, THF, gamma butyrolactone, pyrrolidones, hydroxybutyrate, glutamic acid, levulinic acid, acrylic acid, malonic acid; specialty chemicals such as carotenoids, isoprenoids, itaconic acid; pharmaceuticals and pharmaceutical intermediates such as 7-aminodeacetoxycephalosporanic acid (7-ADCA)/cephalosporin, erythromycin, polyketides, statins, paclitaxel, docetaxel, terpenes, peptides, steroids, omega fatty acids and other such suitable products of interest. Such products are useful in the context of biofuels, industrial and specialty chemicals, as intermediates used to make additional products, such as nutritional supplements, neutraceuticals, polymers, paraffin replacements, personal care products and pharmaceuticals.
Biofuel: A biofuel refers to any fuel that derives from a biological source. Biofuel can refer to one or more hydrocarbons, one or more alcohols (such as ethanol), one or more fatty esters, or a mixture thereof.
Hydrocarbon: The term generally refers to a chemical compound that consists of the elements carbon (C), hydrogen (H) and optionally oxygen (O). There are essentially three types of hydrocarbons, e.g., aromatic hydrocarbons, saturated hydrocarbons and unsaturated hydrocarbons such as alkenes, alkynes, and dienes. The term also includes fuels, biofuels, plastics, waxes, solvents and oils. Hydrocarbons encompass biofuels, as well as plastics, waxes, solvents and oils.

Nucleic Acid Sequences
The present invention provides isolated nucleic acid molecules for genes encoding enzymes, and variants thereof. Exemplary full-length nucleic acid sequences for genes encoding enzymes and the corresponding amino acid sequences are presented in Tables 1 and 2.
In one embodiment, the present invention provides an isolated nucleic acid molecule having a nucleic acid sequence comprising or consisting of a gene coding for an alkane deformylative monooxygenase, a thioesterase, a carboxylic acid reductase, a phosphopanthetheinyl transferase, a long-chain fatty acid CoA-ligase, and/or a long-chain acyl-CoA reductase and homologs, variants and derivatives thereof expressed in a host cell of interest. The present invention also provides a nucleic acid molecule comprising or consisting of a sequence which is a codon-optimized version of the alkane deformylative monooxygenase, a thioesterase, a carboxylic acid reductase, a phosphopanthetheinyl transferase, a long-chain fatty acid CoA-ligase, and/or a long-chain acyl-CoA reductase genes described herein. In a further embodiment, the present invention provides a nucleic acid molecule and homologs, variants and derivatives of the molecule comprising or consisting of a sequence which is a variant of the alkane deformylative monooxygenase, a thioesterase, a carboxylic acid reductase, a phosphopanthetheinyl transferase, a long-chain fatty acid CoA-ligase, and/or a long-chain acyl-CoA reductase gene having at least 80% identity to the wild-type gene. The nucleic acid sequence can be preferably greater than 80%, 85%, 90%, 95%, 98%, 99%, 99.9% or even higher identity to the wild-type gene.
In another embodiment, the nucleic acid molecule of the present invention encodes a polypeptide having an amino acid sequence disclosed in Tables 1 and 2. Preferably, the nucleic acid molecule of the present invention encodes a polypeptide sequence of at least 50%, 60, 70%, 80%, 85%, 90% or 95% identity to the amino acid sequences shown in Tables 1 and 2 and the identity can even more preferably be 96%, 97%, 98%, 99%, 99.9% or even higher.
The present invention also provides nucleic acid molecules that hybridize under stringent conditions to the above-described nucleic acid molecules. As defined above, and as is well known in the art, stringent hybridizations are performed at about 25° C. below the thermal melting point (Tm) for the specific DNA hybrid under a particular set of conditions, where the Tm is the temperature at which 50% of the target sequence hybridizes to a perfectly matched probe. Stringent washing is performed at temperatures about 5° C. lower than the Tm for the specific DNA hybrid under a particular set of conditions.
Nucleic acid molecules comprising a fragment of any one of the above-described nucleic acid sequences are also provided. These fragments preferably contain at least 20 contiguous nucleotides. More preferably the fragments of the nucleic acid sequences contain at least 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100 or even more contiguous nucleotides.
The nucleic acid sequence fragments of the present invention display utility in a variety of systems and methods. For example, the fragments may be used as probes in various hybridization techniques. Depending on the method, the target nucleic acid sequences may be either DNA or RNA. The target nucleic acid sequences may be fractionated (e.g., by gel electrophoresis) prior to the hybridization, or the hybridization may be performed on samples in situ. One of skill in the art will appreciate that nucleic acid probes of known sequence find utility in determining chromosomal structure (e.g., by Southern blotting) and in measuring gene expression (e.g., by Northern blotting). In such experiments, the sequence fragments are preferably detectably labeled, so that their specific hydridization to target sequences can be detected and optionally quantified. One of skill in the art will appreciate that the nucleic acid fragments of the present invention may be used in a wide variety of blotting techniques not specifically described herein.
It should also be appreciated that the nucleic acid sequence fragments disclosed herein also find utility as probes when immobilized on microarrays. Methods for creating microarrays by deposition and fixation of nucleic acids onto support substrates are well known in the art. Reviewed in DNA Microarrays: A Practical Approach (Practical Approach Series), Schena (ed.), Oxford University Press (1999) (ISBN: 0199637768); Nature Genet. 21(1)(suppl):1-60 (1999); Microarray Biochip Tools and Technology, Schena (ed.), Eaton Publishing Company/BioTechniques Books Division (2000) (ISBN: 1881299376), the disclosures of which are incorporated herein by reference in their entireties. Analysis of, for example, gene expression using microarrays comprising nucleic acid sequence fragments, such as the nucleic acid sequence fragments disclosed herein, is a well-established utility for sequence fragments in the field of cell and molecular biology. Other uses for sequence fragments immobilized on microarrays are described in Gerhold et al., Trends Biochem. Sci. 24:168-173 (1999) and Zweiger, Trends Biotechnol. 17:429-436 (1999); DNA Microarrays: A Practical Approach (Practical Approach Series), Schena (ed.), Oxford University Press (1999) (ISBN: 0199637768); Nature Genet. 21(1)(suppl):1-60 (1999); Microarray Biochip: Tools and Technology, Schena (ed.), Eaton Publishing Company/BioTechniques Books Division (2000) (ISBN: 1881299376), the disclosure of each of which is incorporated herein by reference in its entirety.
As is well known in the art, enzyme activities can be measured in various ways. For example, the pyrophosphorolysis of OMP may be followed spectroscopically (Grubmeyer et al., (1993) J. Biol. Chem. 268:20299-20304). Alternatively, the activity of the enzyme can be followed using chromatographic techniques, such as by high performance liquid chromatography (Chung and Sloan, (1986) J. Chromatogr. 371:71-81). As another alternative the activity can be indirectly measured by determining the levels of product made from the enzyme activity. These levels can be measured with techniques including aqueous chloroform/methanol extraction as known and described in the art (Cf. M. Kates (1986) Techniques of Lipidology; Isolation, analysis and identification of Lipids. Elsevier Science Publishers, New York (ISBN: 0444807322)). More modern techniques include using gas chromatography linked to mass spectrometry (Niessen, W. M. A. (2001). Current practice of gas chromatography—mass spectrometry. New York, N.Y.: Marcel Dekker. (ISBN: 0824704738)). Additional modern techniques for identification of recombinant protein activity and products including liquid chromatography-mass spectrometry (LCMS), high performance liquid chromatography (HPLC), capillary electrophoresis, Matrix-Assisted Laser Desorption Ionization time of flight-mass spectrometry (MALDI-TOF MS), nuclear magnetic resonance (NMR), near-infrared (NIR) spectroscopy, viscometry (Knothe, G (1997) Am. Chem. Soc. Symp. Series, 666: 172-208), titration for determining free fatty acids (Komers (1997) Fett/Lipid, 99(2): 52-54), enzymatic methods (Bailer (1991) Fresenius J. Anal. Chem. 340(3): 186), physical property-based methods, wet chemical methods, etc. can be used to analyze the levels and the identity of the product produced by the organisms of the present invention. Other methods and techniques may also be suitable for the measurement of enzyme activity, as would be known by one of skill in the art.

The polypeptides of the present invention also include fusions between the above-described polypeptide sequences and heterologous polypeptides. The heterologous sequences can, for example, include sequences designed to facilitate purification, e.g. histidine tags, and/or visualization of recombinantly-expressed proteins. Other non-limiting examples of protein fusions include those that permit display of the encoded protein on the surface of a phage or a cell, fusions to intrinsically fluorescent proteins, such as green fluorescent protein (GFP), and fusions to the IgG Fc region.

Yet other suitable organisms include synthetic cells or cells produced by synthetic genomes as described in Venter et al. US Pat. Pub. No. 2007/0264688, and cell-like systems or synthetic cells as described in Glass et al. US Pat. Pub. No. 2007/0269862.
Still, other suitable organisms include microorganisms that can be engineered to fix carbon dioxide bacteria such as Escherichia coli, Acetobacter aced, Bacillus subtilis, yeast and fungi such as Clostridium ljungdahlii, Clostridium thermocellum, Penicillium chrysogenum, Pichia pastoris, Saccharomyces cerevisiae, Schizosaccharomyces pombe, Pseudomonas fluorescens, or Zymomonas mobilis. 
A suitable organism for selecting or engineering is capable of autotrophic fixation of CO2 to products. This would cover photosynthesis and methanogenesis. Acetogenesis, encompassing the three types of CO2 fixation; Calvin cycle, acetyl-CoA pathway and reductive TCA pathway is also covered. The capability to use carbon dioxide as the sole source of cell carbon (autotrophy) is found in almost all major groups of prokaryotes. The CO2 fixation pathways differ between groups, and there is no clear distribution pattern of the four presently-known autotrophic pathways. See, e.g., Fuchs, G. 1989. Alternative pathways of autotrophic CO2 fixation, p. 365-382. In H. G. Schlegel, and B. Bowien (ed.), Autotrophic bacteria. Springer-Verlag, Berlin, Germany. The reductive pentose phosphate cycle (Calvin-Bassham-Benson cycle) represents the CO2 fixation pathway in almost all aerobic autotrophic bacteria, for example, the cyanobacteria.
Alkane production via engineered cyanobacteria, e.g., a Synechococcus or Thermosynechococcus species, is preferred. Other preferred organisms include Synechocystis, Klebsiella oxytoca, Escherichia coli or Saccharomyces cerevisiae. Other prokaryotic, archaea and eukaryotic host cells are also encompassed within the scope of the present invention.
In some aspects, alkane production via a photosynthetic organism can be carried out using the compositions, materials, and methods described in: PCT/US2009/035937 (filed Mar. 3, 2009); and PCT/US2009/055949 (filed Sep. 3, 2009); each of which is herein incorporated by reference in its entirety, for all purposes.
Carbon-Based Products of Interest: Hydrocarbons & Alcohols
In various embodiments of the invention, desired hydrocarbons and/or alcohols of certain chain length or a mixture thereof can be produced. In certain aspects, the host cell produces at least one of the following carbon-based products of interest: medium chain-length alkanes such as heptane, nonane, and/or undecane. In other aspects, the carbon chain length ranges from C2 to C20. Accordingly, the invention provides production of various chain lengths of alkanes suitable for use as fuels & chemicals.
In preferred aspects, the methods provide culturing host cells for direct product secretion for easy recovery without the need to extract biomass. These carbon-based products of interest are secreted directly into the medium. Since the invention enables production of various defined chain length of hydrocarbons and alcohols, the secreted products are easily recovered or separated. The products of the invention, therefore, can be used directly or used with minimal processing.
Fuel Compositions
In various embodiments, compositions produced by the methods of the invention are used as fuels. Such fuels comply with ASTM standards, for instance, standard specifications for diesel fuel oils D 975-09b, and Jet A, Jet A-1 and Jet B as specified in ASTM Specification D. 1655-68. Fuel compositions may require blending of several products to produce a uniform product. The blending process is relatively straightforward, but the determination of the amount of each component to include in a blend is much more difficult. Fuel compositions may, therefore, include aromatic and/or branched hydrocarbons, for instance, 75% saturated and 25% aromatic, wherein some of the saturated hydrocarbons are branched and some are cyclic. Preferably, the methods of the invention produce an array of hydrocarbons, such as C2-C17 or C10-C15 to alter cloud point. Furthermore, the compositions may comprise fuel additives, which are used to enhance the performance of a fuel or engine. For example, fuel additives can be used to alter the freezing/gelling point, cloud point, lubricity, viscosity, oxidative stability, ignition quality, octane level, and flash point. Fuels compositions may also comprise, among others, antioxidants, static dissipater, corrosion inhibitor, icing inhibitor, biocide, metal deactivator and thermal stability improver.
In addition to many environmental advantages of the invention such as CO2 conversion and renewable source, other advantages of the fuel compositions disclosed herein include low sulfur content, low emissions, being free or substantially free of alcohol and having high cetane number.
Example 1
Crude Extract of E. coli Cells Overexpressing acrM Convert Lauroyl-CoA to Dodecanal and Decanoyl-CoA to Decanal
Acinetobacter sp. M-1 acyl coenzyme A reductase, acrM, was codon-optimized for E. coli expression and synthesized by DNA2.0 (Menlo Park, CA; SEQ ID NO. 1) with a NdeI site on the 5′ end and an EcoRI site on the 3′ end. The obtained gene was subcloned into a pET28a vector (Novagen) by digestion with NdeI and EcoRI and subsequent ligation. The resulting plasmid, pET28a-acrM (SEQ ID NO. 2), containing an N-terminal His6-tagged acrM (“His6” disclosed as SEQ ID NO: 18), was transformed into a BL21(DE3) E. coli strain, which was subsequently grown with shaking in Luria-Bertani medium supplemented with 100 μg/mL of kanomycin in a volume of 1 L to OD600 =0.8 before induction with 0.25 mM IPTG for 5 hours in a 2-L shaker flask at 37° C. An SDS-PAGE gel demonstrating the overexpression of AcrM protein in pET28a-acrM containing BL21(DE3) E. coli cells is shown in FIG. 1.
The E. coli cells containing overexpressed AcrM were collected by centrifugation, resuspended in HEPES buffer (100 mM HEPES, 10% glycerol, pH 7.5) at a 1:3 (w/v) ratio and lysed by sonication. 200 μL of buffer solution containing 100 μL total lysate, 1 mM acyl-CoA, 3 mM NADH (Sigma-Aldrich), 100 mM HEPES, 10% glycerol at pH 7.5 was incubated at 37° C. for 30 min, extracted with 100 μL ethyl acetate and analyzed by GC/MS equipped with a HP-5 ms column (Agilent, Santa Clara, Calif.). Total ion chromatography (TIC) indicated the detection of aldehydes produced from corresponding acyl-CoA substrates by the AcrM-containing cell extract in the presence of supplemented NADH, as shown in FIG. 2.
Example 2
Feeding Fatty Acid to Svnechococcus Sp. PCC 7002 Strain Expressing adm-carB-entD Results in Detection of Corresponding Aldehyde and Alkane
The carboxylic acid reductase (carB) gene (SEQ ID NO. 3) was PCR-amplified from Mycobacterium smegmatis and verified by sequencing with multiple primers by Genewiz (South Plainfield, N.J.). Cyanothece adm, E. coli leaderless tesA and E. coli entD genes were codon-optimized for E. coli overexpression and synthesized by DNA 2.0 (Menlo Park, Calif.; SEQ ID NO. 4 and 5) with an individual ribosome binding site in front of each gene. All four genes were subcloned into a pUC 19 vector containing an ammonia-repressible P(nir07) promoter, upstream/downstream homology regions, and a spectinomycin marker. The resulting plasmid, pAQ3::P(nir07)-adm-carB-tesA-entD-SpecR (SEQ ID NO. 6), was transformed into wild-type Synechococcus sp. PCC 7002 and segregated in the presence of spectinomycin.
The expression and activity of the Adm, CarB, TesA, and EntD proteins were demonstrated by detection of tridecane and pentadecane in the transformed Synechococcus sp. PCC 7002 strain by GC/FID (FIG. 3).
The Synechococcus sp. PCC 7002 cultures were grown to OD730 ̃5 before 1 mM fatty acid (100 mM stock in ethanol) was added and were then shaken at 150 rpm, 37° C. for  ̃3 hours in the absence (lauric acid feeding) or presence (octanoic acid and decanoic acid feeding) of a pentadecane overlay (6 mL culture with 1 mL overlay). The pentadecane overlay from the octanoic acid-fed culture (FIGS. 4A and 4D), or decanoic acid culture (FIGS. 4B and 4E) was analyzed by GC/MS equipped with an HP-5 ms column. For the lauric acid feeding assay, 1 mL culture was extracted with 400 μL hexane by vortexing for 1 min before being analyzed by GC/MS (FIG. 4C, 4F). Note that the pAQ3::P(nir07)-adm-carB-tesA-entD-SpecR expressing Synechococcus sp. PCC 7002 strain can produce a detectable level of undecane even without feeding dodecanoic acid.
Example 3
Synechococcus Sp. PCC 7002 Strain Expressing adm-carB-fatB2-entD Results in Increased Detection of Nonane in Pentadecane Overlay
The E. coli leaderless tesA of pAQ3::P(nir07)-adm-carB-tesA-entD-SpecR, was replaced by Cuphea hookeriana leaderless fatB2 (a medium-chain acyl-ACP thioesterase), which was codon-optimized for E. coli overexpression and synthesized by DNA 2.0 (Menlo Park, Calif.; SEQ ID NO. 7), with an individual ribosome binding site in front of the gene, a 5′ Kpn I restriction site and a 3′ Hind III restriction site. The resulting plasmid, pAQ3::P(nir07)-adm-carB-fatB2-entD-SpecR (SEQ ID NO. 8), was transformed into wild-type Synechococcus sp. PCC 7002 and segregated in the presence of spectinomycin.
The wild type Synechococcus sp. PCC 7002 and pAQ3::P(nir07)-adm-carB-fatB2-entD-SpecR expressing Synechococcus sp. PCC 7002 cultures (35 mL) were grown to OD730 ̃3 (in the presence of 2 mM urea) before a 10 mL pentadecane overlay was added. The cultures were shaken at 150 rpm, 37° C. for 3 more days continuously. 100 μL pentadecane overlay samples from each flask were taken 12 hours (FIG. 5A) or 72 hours (FIG. 5B) after pentadecane addition, respectively, and analyzed directly by GC/FID equipped with a 20 meter hp-5 ms column. An increase of nonane production was detected in the pAQ3::P(nir07)-adm-carB-fatB2-entD-SpecR expressing Synechococcus sp. PCC 7002 cultures but not in the wild type control ones. A relative increase in octane and heptanes production was also detected in the pAQ3::P(nir07)-adm-carB-fatB2-entD-SpecR expressing Synechococcus sp. PCC 7002 cultures (data not shown).
Example 4
Medium Chain-Length Alkane Production
One or more recombinant genes encoding one or more enzymes having enzyme activities which catalyze the production of medium chain-length alkanes are identified and selected. The enzyme activities include: an alkane deformylative monooxygenase activity, a thioesterase activity, a carboxylic acid reductase activity, and a phosphopanthetheinyl transferase activity, a long-chain fatty acid CoA-ligase activity, and/or a long-chain acyl-CoA reductase activity. Such genes and enzymes can be those described in Tables 1 and 2.
The selected genes are cloned into an expression vector. For example, adm-carB-entD-fatB or adm-acrM-fadD-fatB (or combinations of homologs thereof) are cloned into one or more vectors. See FIG. 6. The genes can be under inducible control (such as the urea-repressible nir07 promoter or the cumate-inducible cum02 promoter). The genes may or may not be expressed operonically; and one or more of the genes can be placed under constitutive control such that when the other gene(s) are induced, the genes under constitutive control are already expressed. For example, one might express adm, carB, and entD constitutively while placing fatty-acid-generating fatB under inducible control; thus when fatty acids are made by fatB after induction, the remainder of the pathway is already present.
One or more vectors are selected and transformed into a microorganism (e.g., cyanobacteria). The cells are grown to a suitable optical density. In some instances cells are grown to a suitable optical density in an uninduced state, and then an induction signal is applied to commence alkane production.
Alkanes are produced by the transformed cells. The alkanes generally have 7, 8, 9, 10, or 11 carbon atoms. In some instances, alkanes are detected. In some instances, alkanes are quantified. In some instances, alkanes are collected.
In some aspects, a thioesterase such as fatB can be used. To test downstream of fatB, fatty acids of various chain lengths are fed along with inorganic carbon (e.g., CO2) to cells, and alkane production is monitored. After fatB addition, cells are provided with inorganic carbon (e.g., CO2) and alkane production is monitored.

## Claims

1. An engineered cyanobacterium, wherein the engineered cyanobacterium comprises recombinant genes encoding an alkane deformylative monooxygenase having EC number 4.1.99.5, a thioesterase having EC number 3.1.2.14, and a carboxylic acid reductase having EC number 1.2.99.6, wherein the alkane deformylative monooxygenase is encoded by adm, the thioesterase is encoded by fatB or fatB2, and the carboxylic acid reductase is encoded by carB, wherein the thioesterase converts C(8-12) acyl-ACP to C(8-12) fatty acid, wherein the carboxylic acid reductase converts C(8-12) fatty acid to C(8-12) aldehyde, wherein the alkane deformylative monooxygenase converts C(8-12) aldehyde to C(7-11) alkane, and wherein the engineered cyanobacterium produces at least one of heptane, nonane, and undecane in an amount greater than an otherwise identical cyanobacterium, cultured under identical conditions, but lacking recombinant genes encoding alkane deformylative monooxygenase, thioesterase, and carboxylic acid reductase.

2. The engineered cyanobacterium of claim 1, wherein the cyanobacterium further comprises one or more recombinant genes encoding a phosphopanthetheinyl transferase.

3. The engineered cyanobacterium of claim 1, wherein the cyanobacterium further comprises one or more recombinant genes encoding a phosphopanthetheinyl transferase having EC number 2.7.8.7.

4. The engineered cyanobacterium of claim 3, wherein the phosphopanthetheinyl transferase is encoded by entD.

5. The engineered cyanobacterium of claim 1, wherein the cyanobacterium is a thermotolerant cyanobacterium, or a Synechococcus species.

6. The engineered cyanobacterium of claim 1, wherein expression of an operon comprising one or more of the recombinant genes is controlled by a recombinant promoter, and wherein the promoter is constitutive or inducible.

7. The engineered cyanobacterium of claim 1, wherein the cyanobacterium produces alkanes 7 to 11 carbon atoms in length; or alkanes 7, 8, 9, 10, or 11 carbon atoms in length.

8. A cell culture comprising a culture medium and the cyanobacterium of claim 1.

9. A method for producing hydrocarbons, comprising:
culturing an engineered cyanobacterium of claim 1 in a culture medium, wherein the engineered cyanobacterium produces increased amounts of alkanes relative to an otherwise identical cyanobacterium, cultured under identical conditions, but lacking the recombinant genes.

10. A method for producing hydrocarbons, comprising:
(i) culturing an engineered cyanobacterium of claim 1 in a culture medium; and
(ii) exposing the engineered cyanobacterium to light and inorganic carbon, wherein said exposure results in the conversion of said inorganic carbon by the cyanobacterium into alkanes, wherein the alkanes are produced in an amount greater than that produced by an otherwise identical cyanobacterium, cultured under identical conditions, but lacking the recombinant genes.

11. The engineered cyanobacterium of claim 1, wherein the cyanobacterium produces alkanes 9 carbon atoms in length.

12. The engineered cyanobacterium of claim 1, wherein the cyanobacterium produces alkanes 11 carbon atoms in length.

13. The engineered cyanobacterium of claim 1, wherein the cyanobacterium produces alkanes 9 and 11 carbon atoms in length.

14. The method of claim 9, wherein the alkanes produced are 9 or 11 carbons in length.

15. The method of claim 10, wherein the alkanes produced are 9 or 11 carbons in length.

16. The engineered cyanobacterium of claim 1, wherein the predominant alkane produced by the cyanobacterium is nonane.
