Enzyme Information
| 6.3.5.2 |
GMP synthase (glutamine-hydrolyzing).
based on mapping to UniProt P04079
ATP + XMP + L-glutamine + H(2)O = AMP + diphosphate + GMP + L-glutamate.
-!- Involved in the de novo biosynthesis of guanosine nucleotides. -!- An N-terminal glutaminase domain binds L-glutamine and generates ammonia, which is transferred by a substrate-protective tunnel to the ATP-pyrophosphatase domain. -!- The enzyme can catalyze the second reaction alone in the presence of ammonia. -!- Formerly EC 6.3.4.1.
