In enzymology a NAD+ synthase (glutamine-hydrolysing) (EC 6.3.5.1) is an enzyme that catalyzes the chemical reactionATP + deamido-NAD+ + L-glutamine + H2O AMP + diphosphate + NAD+ + L-glutamateThe 4 substrates of this enzyme are ATP deamido-NAD+ L-glutamine and H2O whereas its 4 products are AMP diphosphate NAD+ and L-glutamate.This enzyme belongs to the family of ligases specifically those forming carbon-nitrogen bonds carbon-nitrogen ligases with glutamine as amido-N-donor.
