3.5.99.7 | 1-aminocyclopropane-1-carboxylate + H2O = 2-oxobutanoate + NH3 |
ring cleavage is induced by a nucleophilic attack at the pro-S-beta-methylene carbon of substrate, with Tyr294 as the nucleophile. Alternatively, ring opening is acid-catalyzed and may be facilitated by charge relay through pyridoxal 5-phosphate, with Tyr294 as general acid |
