== Function ==
 +
[https://www.uniprot.org/uniprot/PSIM_PSICU PSIM_PSICU] N-methyltransferase; part of the gene cluster that mediates the biosynthesis of psilocybin, a psychotropic tryptamine-derived natural product (PubMed:28763571, PubMed:31150155). The first step in the pathway is the decarboxylation of L-tryptophan to tryptamine by the decarboxylase psiD (PubMed:28763571, PubMed:31150155). 4-hydroxy-L-tryptophan is accepted as substrate by psiD as well (PubMed:28763571). The cytochrome P450 monooxygenase psiH then converts tryptamine to 4-hydroxytryptamine (PubMed:28763571). The kinase psiK catalyzes the 4-O-phosphorylation step by converting 4-hydroxytryptamine into norbaeocystin (PubMed:28763571, PubMed:31150155). The methyltransferase psiM then catalyzes iterative methyl transfer to the amino group of norbaeocystin to yield psilocybin via a monomethylated intermediate, baeocystin (PubMed:28763571, PubMed:31150155). 4-hydroxy-6-methyl-l-tryptophancan also be converted the decarboxylase PsiD, kinase PsiK, and methyltransferase PsiM into respectively 6-methyl-norbaeocystin, 6-methylbaeocystin, and 6-methylpsilocybin (PubMed:31150155).<ref>PMID:28763571</ref> <ref>PMID:31150155</ref>
