Enzyme Commission Primary Name: trans-aconitate 2-methyltransferase

Enzyme Commission Summary:
Also catalyzes the formation of the methyl monoester of cis- aconitate, isocitrate and citrate, but more slowly.
While the enzyme from Escherichia coli forms (E)-3- (methoxycarbonyl)-pent-2-enedioate as the product, that from Saccharomyces cerevisiae forms (E)-2-(methoxycarbonylmethyl) butenedioate and is therefore classified as a separate enzyme (cf. EC
