The present disclosure provides engineered polypeptides having imine reductase activity, polynucleotides encoding the engineered imine reductases, host cells capable of expressing the engineered imine reductases, and methods of using these engineered polypeptides with a range of ketone and amine substrate compounds to prepare secondary and tertiary amine product compounds.

The use of a cytochrome P-450 enzyme comprising SEQ ID NO: 110, or a variant enzyme having at least 70% identity thereto and having CYP-450 activity, for the hydroxylation of an organic compound, wherein the amino acid residue at position 291 is not threonine.

A semisynthetic method of preparing neosaxitoxin from cultures of the dinoflagellate Gymnodinium catenatum is described. The scalable method includes the reductive desulfonation of an unresolved mixture of toxin C3 and toxin C4 and mild acid hydrolysis of the resulting gonyautoxin 6 (GTX6) to provide the neosaxitoxin.

The present invention generally relates to methods of producing one or more indole diterpene compounds in the epoxy janthitrem biosynthetic pathway and polynucleotides, polypeptides, expression constructs and host cells useful in the production of one or more indole diterpene compounds, and methods of using same to confer a benefit to an organism, such as increased insect pest resistance.

Engineered non-plant cells that produce a benzylisoquinoline alkaloid product that is a derivative of canadine along a metabolic pathway that converts canadine, or an analog of canadine, to a noscapinoid product are provided. Methods of culturing engineered non-plant cells that produce a noscapinoid product and pharmaceutical compositions are also provided.

The present invention provides an enzymatic means for the biosynthetic production of caffeine. The present invention provides biosynthetic methods for production of caffeine comprising: providing guanine, a guanine deaminase, at least one methyl transferase, and a methyl donor; contacting the guanine with the gtheuanine deaminase to produce xanthine; contacting the xanthine with the methyl transferase and a methyl donor, under conditions wherein the xanthine is methylated, to produce a monomethylxanthine; contacting the monomethylxanthine with the methyl transferase and a methyl donor, under conditions wherein the monomethylxanthine is methylated, to produce a dimethylxanthine; and contacting the dimethylxanthine with the methyl transferase and a methyl donor, under conditions wherein the dimethylxanthine is methylated, to produce caffeine (i.e., 1,3,7-trimethylxanthine).
