3.5.99.7
Description 1-aminocyclopropane-1-carboxylate deaminase.
Alternative names 1-aminocyclopropane carboxylic acid deaminase;
ACC deaminase.
Catalyzed reaction 1-aminocyclopropane-1-carboxylate + H(2)O = 2-oxobutanoate + NH(3).
Cofactor Pyridoxal-phosphate.
Comments Its introduction has been used to make fruit ripening dependent on externally added ethylene, as it removes the substrate for endogenous ethylene formation.
Formerly EC 4.1.99.4.
PDB 1F2D; 1TYZ;
Organisms -Eubacteria -Fungi
