Protein: Picrinine-N-methytransferase (A0A075D5I4)
Organism: Rauvolfia serpentina (Serpentine wood) (Ophioxylon serpentinum)
Function: S-adenosyl-L-methionine-dependent N-methyltransferase involved in the biosynthesis of biologically active monoterpenoid indole alkaloids (MIAs) natural products including vindoline . Catalyzes the conversion of picrinine to N- methylpicrinine (ervincine). Accepts also, with low efficiency, 21-hydroxycyclolochnericine and norajmaline as substrates
Subcellular location: Vacuole membrane
