- S-adenosyl-L-methionine + 12-hydroxydihydrochelirubine S-adenosyl-L-homocysteine + dihydromacarpine
Thus, the two substrates of this enzyme are S-adenosyl methionine and 12-hydroxydihydrochelirubine, whereas its two products are S-adenosylhomocysteine and dihydromacarpine.
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:12-hydroxydihydrochelirubine 12-O-methyltransferase. This enzyme participates in alkaloid biosynthesis i.
