Cytochrome P450 monooxygenase; part of the DMATS1 gene cluster that mediates the biosynthesis of a reversely N-prenylated monomeric L-tryptophan (r-N-DMAT) (PubMed:28295904). Seems not to contribute to the final DMATS1 product (PubMed:28295904). Expression is negaticely regulated by the global nitrogen regulator areA. Does not alter the amount of produced r-N-DMAT. Belongs to the cytochrome P450 family.
