Trans-resveratrol di-O-metiltransferaza (EC 2.1.1.240, ROMT, resveratrolna O-metiltransferaza, pterostilbenska sintaza) je enzim sa sistematskim imenom S-adenozil-L-metionin:trans-resveratrol 3,5-O-dimetiltransferaza.[1] Ovaj enzim katalizuje sledeću hemijsku reakciju
- 2 S-adenozil-L-metionin + trans-resveratrol 2 S-adenozil-L-homocistein + pterostilben (sveukupna reakcija)
- (1a) S-adenozil-L-metionin + trans-resveratrol S-adenozil-L-homocistein + 3-metoksi-4',5-dihidroksi-trans-stilben
- (1b) S-adenozil-L-metionin + 3-metoksi-4',5-dihidroksi-trans-stilben S-adenozil-L-homocistein + pterostilben
Ovaj enzim katalizuje biosintezu pterostilbena i resveratrola.
