Enzyme Information

Glutamin-(asparagin-)ase.
based on mapping to UniProt P10182
(1) L-glutamine + H(2)O = L-glutamate + NH(3). (2) L-asparagine + H(2)O = L-aspartate + NH(3).
-!- L-asparagine is hydrolyzed at 0.8 of the rate of L-glutamine. -!- The D-isomers are also hydrolyzed, more slowly. -!- Cf. EC 3.5.1.1 and EC 3.5.1.2.
