Reaction: 1-aminocyclopropane-1-carboxylate + H2O = 2-oxobutanoate + NH3
Other name(s): 1-aminocyclopropane-1-carboxylate endolyase (deaminating)
Systematic name: 1-aminocyclopropane-1-carboxylate aminohydrolase (isomerizing)
Comments: A pyridoxal 5'-phosphate enzyme. Its introduction has been used to make fruit ripening dependent on externally added ethylene, as it removes the substrate for endogenous ethylene formation.
