IUBMB Enzyme Nomenclature


Accepted name: pavine N-methyltransferase

Reaction: S-adenosyl-L-methionine + (±)-pavine = S-adenosyl-L-homocysteine + N-methylpavine

Other name(s): PavNMT

Systematic name: S-adenosyl-L-methionine:(±)-pavine N-methyltransferase

Comments: The enzyme, isolated from the plant Thalictrum flavum, also methylates (R,S)-stylopine and (S)-scoulerine (11%) with lower activity (14% and 11%, respectively).
