The present invention relates generally to genes and polypeptides which have utility in glycosylating quillaic acid in host cells, including enzymes capable of successive glycosylation at the C-3 position of quillaic acid. The invention further relates to systems, methods and products employing the same.

Described herein are CB5 polypeptides for the biosynthesis of oxygenated hydrocarbons in modified host cells.

The present invention relates to a recombinant microorganism which is capable of expressing a cytochrome P450 reductase (CPR) and, optionally, a cytochrome P450 enzyme (CYP) and which is capable of overexpressing a Ice2p comprising the amino acid sequence set out in SEQ ID NO: 2 or a sequence having at least 50% sequence identity thereto. The invention further relates to use of Ice2p to stabilize expression of a cytochrome P450 reductase in a recombinant microorganism.

Recombinant microorganisms, plants, and plant cells are disclosed that have been engineered to express novel recombinant genes encoding steviol biosynthetic enzymes and UDP-glycosyltransferases (UGTs). Such microorganisms, plants, or plant cells can produce steviol or steviol glycosides, e.g., rubusoside or Rebaudioside A, which can be used as natural sweeteners in food products and dietary supplements.

The present invention provides improved P450-BM3 variants with improved activity. In some embodiments, the P450-BM3 variants exhibit improved activity over a wide range of substrates.

The present invention relates to methods for synthesizing mixed disulfide conjugates of thienopyridine compounds with a genetically engineered variant of cytochrome P450 BM3 or CYP102A1 as a catalyst, and belongs to the field of chemical synthesis.

This disclosure relates to recombinant microbes, systems, and methods useful in the production of psilocybin and dimethyltryptarme (DMT). The disclosure relates to modifications and optimizations to genes and enzymes directly involved in the psilocybin and DMT pathway for the production of psilocybin and DMT in a host cell. The disclosure also relates to modifications and optimizations to genes and enzymes in the host cell and medium for psilocybin and DMT production in E. coli. The present disclosure also relates to a semi-synthetic method of producing psilocybin.

The disclosure relates, in some aspects, to compositions and methods useful for production of nitrated aromatic molecules. The disclosure is based, in part, on whole cell systems expressing artificial fusion proteins comprising cytochrome P450 enzymes linked to reductase enzymes. In some aspects, the disclosure relates to methods of producing nitrated aromatic molecules in whole cell systems having artificial fusion proteins comprising cytochrome P450 enzymes linked to reductase enzymes.

The present invention provides improved P450-BM3 variants with improved activity. In some embodiments, the P450-BM3 variants exhibit improved activity over a wide range of substrates.

The present invention relates to a production method of (R)-reticuline including: a step for obtaining a recombinant host cell by inserting, into a host cell, a gene 1 which is composed of a nucleotide sequence having at least 70% homology to a nucleotide sequence of SEQ ID NO: 2 and which is DNA encoding a protein having an enzymatic activity of CYP80Y2, and a gene 2 which is composed of a nucleotide sequence having at least 70% homology to a nucleotide sequence of SEQ ID NO: 3 and which is DNA encoding a protein having an enzymatic activity of oxidoreductase; a step for expressing, in the recombinant host cell, the protein having the enzymatic activity of CYP80Y2 and the protein having the enzymatic activity of oxidoreductase; and a step for producing (R)-reticuline from (S)-reticuline by using the recombinant host cell.
