A major point of regulation occurs at the generally rate-limiting step in biosynthesis, catalyzed by the enzyme ACC synthase (ACS). ACS is encoded by a multigene family, and different members show distinct patterns of expression during …
ACC Synthase is also competitively inhibited by aminoethoxyvinylglycine (AVG) and aminooxyacetic acid (AOA), inhibitors to many pyridoxal phosphate-mediated enzymic reactions. They are natural toxins that cause slow binding inhibition by interfering with the coenzyme pyridoxal phosphate.
