S-adenosyl-L-methionine + trans-aconitate S-adenosyl-L-homocysteine + (E)-2-(methoxycarbonylmethyl)butenedioate

Thus, 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. The systematic name of this enzyme class is S-adenosyl-L-methionine:(E)-prop-1-ene-1,2,3-tricarboxylate 3'-O-methyltransferase.
