Trans-resveratrol di-O-methyltransferase (EC 2.1.1.240, ROMT, resveratrol O-methyltransferase, pterostilbene synthase) is an enzyme with systematic name S-adenosyl-L-methionine:trans-resveratrol 3,5-O-dimethyltransferase.[1] This enzyme catalyses the following chemical reaction
- 2 S-adenosyl-L-methionine + trans-resveratrol 2 S-adenosyl-L-homocysteine + pterostilbene (overall reaction)
- (1a) S-adenosyl-L-methionine + trans-resveratrol S-adenosyl-L-homocysteine + 3-methoxy-4',5-dihydroxy-trans-stilbene
- (1b) S-adenosyl-L-methionine + 3-methoxy-4',5-dihydroxy-trans-stilbene S-adenosyl-L-homocysteine + pterostilbene
The enzyme catalyses the biosynthesis of pterostilbene from resveratrol.
