UniProtKB - P9WJJ3 (NADE_MYCTU)
Protein
Glutamine-dependent NAD(+) synthetase
Gene
nadE
Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Status
Functioni
Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source. In vitro, can also use ammonia with comparable specific activity.3 Publications
Catalytic activityi
- ATP + deamido-NAD+ + H2O + L-glutamine = AMP + diphosphate + H+ + L-glutamate + NAD+UniRule annotation3 PublicationsEC:6.3.5.1UniRule annotation3 Publications
Activity regulationi
The formation of the intermediates complex at the synthetase domain stimulates the glutaminase activity.1 Publication
Kineticsi
kcat is 0.55 sec(-1) for glutamine-dependent activity. kcat is 2.8 sec(-1) for ammonia-dependent activity.1 Publication
