Accepted name: NAD+ synthase
Reaction: ATP + deamido-NAD+ + NH3 = AMP + diphosphate + NAD+
Other name(s): NAD synthetase; NAD synthase; nicotinamide adenine dinucleotide synthetase; diphosphopyridine nucleotide synthetase
Systematic name: deamido-NAD+:ammonia ligase (AMP-forming)
Comments: L-Glutamine also acts, more slowly, as amido-donor [cf. EC].
