Abstract: The invention provides an engineered carboxylic acid reductase (CAR) enzyme, a nucleic acid encoding the CAR enzyme, and a non-naturally occurring microbial organism comprising an exogenous nucleic acid encoding the CAR, an engineered transaminase (TA) enzyme, and/or a hexamethylenediamine (HMD) transaminase (TA2) enzyme. The invention provides a non-naturally occurring microbial organism that has a 1,6-hexanediol (HDO) pathway with a HDO pathway enzyme expressed in sufficient amounts to produce 6 aminocaproate semi aldehyde, HDO, or both. The invention further provides a non-naturally occurring microbial organism that has an HMD pathway with a HMD pathway enzyme expressed in sufficient amounts to produce 6-aminocaproate semialdehyde, HMD, or both. The invention additionally provides bioderived HMD, 6-aminocaproate semialdehyde, and/or HDO and methods for producing bioderived HMD, 6-aminocaproate semialdehyde, and/or HDO.

Abstract: The invention relates to a non-natural cannabinoid synthase comprising at least one amino acid variation as compared to a wild type cannabinoid synthase ?9-tetrahydrocannabinolic acid synthase (THCAS), comprising three alpha helices (?A, ?B and ?C) where a disulfide bond is not formed between alpha helix ?A and alpha helix ?C, wherein the non-natural cannabinoid synthase catalyzes the oxidative cyclization of cannabigerolic acid (CBGA) into a cannabinoid. The invention further relates to a non-natural ?9-tetrahydrocannabinolic acid synthase (THCAS), a non-natural cannabidiolic acid synthase (CBDAS), and a non-natural cannabichromenic acid synthase (CBCAS) comprising at least one amino acid variation as compared to a wild type THCAS, CBDAS, or CBCAS, respectively, comprising three alpha helices (?A, ?B and ?C) and wherein a disulfide bond is not formed between alpha helix ?A and alpha helix ?C.

Abstract: Disclosed are transaminase (TA) enzymes and nucleic acids encoding them. In some cases, the transaminase enzymes are non-natural, engineered transaminases. Also disclosed are biosynthetic methods and engineered microorganisms that enhance or improve the biosynthesis of 6-aminocaproate, hexamethylenediamine, caproic acid, caprolactone, or caprolactam. The engineered microorganisms include exogenous TA and in some cases engineered TA.
