Reaction: S-adenosyl-L-methionine + trans-resveratrol = S-adenosyl-L-homocysteine + 4'-O-methyl-trans-resveratrol
Other name(s): AcOMT1
Systematic name: S-adenosyl-L-methionine:trans-resveratrol 4'-O-methyltransferase
Comments: The enzyme occurs in the roots and leaves of the plant Acorus calamus (sweet flag). In additon to trans-reveratrol it is active toward isorhapontigenin and shows slight activities toward piceatannol, oxyresveratrol, and pinostilbene.
