L-Vinylglycine is an alternative substrate as well as a mechanism-based inhibitor of 1-aminocyclopropane-1-carboxylate synthase.

L-Vinylglycine (L-VG) has been shown to be a mechanism-based inhibitor of 1-aminocyclopropane-1-carboxylate (ACC) synthase [Satoh, S., and Yang, S. F. (1989) Plant Physiol. 91, 1036-1039] as well as of other pyridoxal phosphate-dependent enzymes. This report demonstrates that L-VG is primarily an alternative substrate for the enzyme. The L-VG deaminase… CONTINUE READING
