Function
function
Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
Catalytic activity
- deamido-NAD+ + L-glutamine + ATP + H2O = L-glutamate + AMP + diphosphate + NAD+ + H+
Pathway
Cofactor biosynthesis; NAD+ biosynthesis; NAD+ from deamido-NAD+ (L-Gln route): step 1/1.
