1-aminocyclopropane-1-carboxylic acid · 1-aminocyclopropane-1-carboxylic acid, 14C-labeled · ACC acid
1-Aminocyclopropane-1-carboxylic acid (ACC) is a disubstituted cyclic α-amino acid in which a three-membered cyclopropane ring is fused to the Cα atom of the amino acid. ACC plays an important role in the biosynthesis of the plant hormone ethylene. It is synthesized by the enzyme ACC synthase ( EC 126.96.36.199) from methionine and converted to ethylene by ACC oxidase (EC 188.8.131.52).
