The method provides for engineered microorganisms that express endogenous and/or exogenous nucleic acid molecules that catalyze the conversion of a carbon source into 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA. The disclosure further provides methods of producing polymers derived from 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA.

A microorganism is transformed to be capable of producing guanidinoacetic acid (GAA). A method can be used for the fermentative production of GAA using such a microorganism. A corresponding method can be used for the fermentative production of creatine.

Enzymes for producing non-straight-chain fatty acids, microorganisms comprising the enzymes, and in vivo and in vitro uses of the enzymes. Provided are enzymes capable of producing various non-straight-chain fatty acids, including branched-chain fatty acids, cyclic fatty acids, and furan-containing fatty acids. The enzymes include RSP2144, RSP1091, and RSP1090 from Rhodobacter sphaeroides and homologs thereof. The enzymes can be purified to produce non-straight-chain fatty acids in vitro or expressed in microorganisms to produce non-straight-chain fatty acids in vivo. The microorganisms can be fine-tuned to produce a specific type of non-straight-chain fatty acid by expressing, overexpressing, or deleting the enzymes in various combinations.

An isoform of the TGF beta receptor II comprising a sequence of about of 80 amino acids and lacking a transmembrane domain; wherein the isoform is a TGF-1 agonist. The isoform comprises the amino acid sequence set forth in SEQ ID No. 12. The isoform may have the amino acid sequence set forth in SEQ ID No. 2 or sequences having at least 85% sequence identity to the sequence set forth in SEQ ID No. 2.

The present disclosure relates to biological processes and systems for the production of isopropanol and/or acetone utilizing modified alcohol dehydrogenases that exhibit increased activity with NADH as a cofactor. The disclosure further relates to polynucleotides and polypeptides of the modified alcohol dehydrogenases, and host cells containing the polynucleotides and expressing the polypeptides.

The disclosure provides recombinant bacterial host cells that metabolize and convert glycerol or volatile fatty acids (VFAs) to poly(3-hydroxybutyrate-co-3-hydroxyvalerate) or PHBV. The disclosure further provides methods of producing PHBV using the recombinant bacteria disclosed herein.

The invention provides a genetically modified micro-organism for intracellular biosynthesis of a cellular metabolite, comprising a synthetic error correction system having a penalty gene, whose expression leads to arrested growth or cell death (e.g. a toxin gene) in combination with a survival gene, whose expression provides an antidote that restores cell viability and normal growth (e.g. a cognate antitoxin gene). Alternatively, the system has a survival gene, alone, whose expression is essential for growth (i.e. essential gene). The synthetic error correction system further comprises a biosensor, whose function is to induce expression of the survival gene which leads to cell growth, only, when the cell produces a pre-defined level of a given metabolite. The invention further encompasses: a method for producing the genetically modified micro-organism; a method for producing a cellular metabolite with the genetically modified micro-organism; and use of the genetically modified micro-organism for producing a cellular metabolite.
