}}Trans-resveratrol di-O-methyltransferase ({{EC number|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.
