The activity of 1-aminocyclopropane carboxylate (ACC) synthase increased rapidly in tomato (Lycopersicon esculentum Mill.) leaf discs after vacuum infiltration, reached a maximum after about 30 minutes, and subsequently decayed with an apparent half-life of about 20 minutes. Aminoethoxyvinylglycine, a known inhibitor of ACC synthase, did not alter the apparent turnover of ACC synthase in vivo although it efficiently blocked inactivation of the enzyme by its substrate S-adenosylmethionine in… CONTINUE READING
