In enzymology a trans-aconitate 3-methyltransferase (EC 2.1.1.145) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + trans-aconitate S-adenosyl-L-homocysteine + (E)-2-(methoxycarbonylmethyl)butenedioateThus the two substrates of this enzyme are S-adenosyl methionine and trans-aconitate whereas its two products are S-adenosylhomocysteine and (E)-2-(methoxycarbonylmethyl)butenedioate.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
