NAD synthetase is an essential enzyme involved in both the de novo biosynthesis and salvage of NAD+, catalyzing the final step of both pathways. Since NAD has a vital role in cell metabolism, the enzyme represents a valid target for the development of new antimycobacterial agents. It can use both glutamine or ammonia as a nitrogen source. Catalytic activity: ATP + deamido-NAD+ + L-glutamine + H2O = AMP + diphosphate + NAD+ + L-glutamate.
