This is a methylation reaction in which the benzylisoquinoline alkaloid, (S)-scoulerine, is converted to (S)-isocorypalmine. The methyl group comes from the cofactor, S-adenosyl methionine (SAM), which becomes S-adenosyl-L-homocysteine (SAH). The enzyme was characterised from Berberis wilsoniae.[1]
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:(S)-scoulerine 9-O-methyltransferase. It is part of the alkaloid biosynthesis pathway.[2]
