Fig. 4From: Biotechnological applications of S-adenosyl-methionine-dependent methyltransferases for natural products biosynthesis and diversificationReactions of promiscuous methyltransferases for small molecule production. a Caffeate O-methyltransferases (COMT) readily accept structurally similar compounds, such as caffeate, 3,4-dihydroxybenzyl alcohol (3,4-DDBA) and resveratrol. b Juvenile hormone acid O-methyltransferase (JHAMT) can methylate C12–C16 fatty acid.
