Identification
Name:E-3-Carboxy-2-pentenedioate 6-methyl ester
DescriptionE-3-carboxy-2-pentenedioate 6-methyl ester is catalyzed by trans-aconitate methyltransferase. The trans-aconitate methyltransferase from the bacterium Escherichia coli catalyzes the monomethyl esterification of trans-aconitate and related compounds. Using two-dimensional (1)H/(13)C nuclear magnetic resonance spectroscopy, we show that the methylation is specific to one of the three carboxyl groups and further demonstrate that the product is the 6-methyl ester of trans-aconitate (E-3-carboxy-2-pentenedioate 6-methyl ester).
