The present disclosure provides engineered transaminase polypeptides for the production of amines, polynucleotides encoding the engineered transaminases, host cells capable of expressing the engineered transaminases, and methods of using the engineered transaminases to prepare compounds useful in the production of active pharmaceutical agents. The present disclosure provides engineered polypeptides having transaminase activity, polynucleotides encoding the polypeptides, methods of the making the polypeptides, and methods of using the polypeptides for the biocatalytic conversion of ketone substrates to amine products. The present enzymes have been engineered to have one or more residue differences as compared to the amino acid sequence of the naturally occurring transaminase of Vibrio fluvialis. In particular, the transaminases of the present disclosure have been engineered for efficient formation of chiral tryptamine derivatives from its corresponding prochiral ketone substrates.

摘要:
This document describes biochemical pathways for producing adipic acid, 6-aminohexanoic acid, 6-hydroxhexanoic acid, hexamethylenediamine, caprolactam, or 1,6-hexanediol by forming one or two terminal functional groups, comprised of carboxyl, amine or hydroxyl group, in a C6 aliphatic backbone substrate. These pathways, metabolic engineering and cultivation strategies described herein rely on the enzymes or homologs accepting methyl ester shielded dicarboxylic acid substrates.
摘要:
The present invention relates to a method for the enzymatic synthesis of enantiomerically enriched (R)-amines of general formula [1][c], from the corresponding ketones of general formula [1][a], by using novel transaminases. These novel transaminases are selected from two different groups: either from a group of some 20 proteins with sequences as specified herein, or from a group of proteins having transaminase activity and isolated from a microorganism selected from the group of organisms consisting of Rahnella aquatilis, Ochrobactrum anthropi, Ochrobactrum tritici, Sinorhizobium morelense, Curtobacterium pusilllum, Paecilomyces lilacinus, Microbacterium ginsengisoli, Microbacterium trichothecenolyticum, Pseudomonas citronellolis, Yersinia kristensenii, Achromobacter spanius, Achromobacter insolitus, Mycobacterium fortuitum, Mycobacterium frederiksbergense, Mycobacterium sacrum, Mycobacterium fluoranthenivorans, Burkholderia sp., Burkholderia tropica, Cosmospora episphaeria, and Fusarium oxysporum.

This document describes biochemical pathways for producing pimelic acid, 7-aminoheptanoic acid, 7-hydroxyheptanoic acid, heptamethylenediamine or 1,7-heptanediol by forming one or two terminal functional groups, each comprised of carboxyl, amine or hydroxyl group, in a C7 aliphatic backbone substrate. These pathways, metabolic engineering and cultivation strategies described herein rely on the C1 elongation enzymes or homolog associated with coenzyme B biosynthesis.

摘要:
The invention provides a non-naturally occurring microbial organism having an adipate, 6-aminocaproic acid or caprolactam pathway. The microbial organism contains at least one exogenous nucleic acid encoding an enzyme in the respective adipate, 6-aminocaproic acid or caprolactam pathway. The invention additionally provides a method for producing adipate, 6-aminocaproic acid or caprolactam. The method can include culturing an adipate, 6-aminocaproic acid or caprolactam producing microbial organism, where the microbial organism expresses at least one exogenous nucleic acid encoding an adipate, 6-aminocaproic acid or caprolactam pathway enzyme in a sufficient amount to produce the respective product, under conditions and for a sufficient period of time to produce adipate, 6-aminocaproic acid or caprolactam.
