PsiM - Norbaeocystin methyltransferase from Psilocybe cubensis

PsiM is a norbaeocystin methyltransferase, which catalyses the conversion of norbaeocystin to psilocybin.

Usage and Biology

PsiM is a native enzyme obtained from Psilocybe cubensis, which is involved in the metabolic biosynthesis of psilocybin from tryptophan. It accepts norbaeocystin as a substrate to yield psilocybin through N,N-dimethylation. Heterologous expression of PsiM has been achieved in Escherichia coli <add strain> in a <expression system>.
