Enzyme Information

3.5.99.10
2-iminobutanoate/2-iminopropanoate deaminase.
based on mapping to UniProt P37552
(1) 2-iminobutanoate + H(2)O = 2-oxobutanoate + NH(3). (2) 2-iminopropanoate + H(2)O = pyruvate + NH(3).
-!- This enzyme, which has been found in all species and tissues examined, catalyzes the hydrolytic deamination of imine intermediates formed by several types of pyridoxal-5'-phosphate-dependent dehydratases, such as EC 4.3.1.19 and EC 4.3.1.17. -!- The reactions, which can occur spontaneously, are accelerated to minimize the cellular damage that could be caused by these reactive intermediates.
