CC -!- FUNCTION: Catalyzes the ATP-dependent amidation of deamido-NAD to form
CC NAD. Uses L-glutamine as a nitrogen source. {ECO:0000256|HAMAP-
CC Rule:MF_02090}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + deamido-NAD(+) + H2O + L-glutamine = AMP + diphosphate +
CC H(+) + L-glutamate + NAD(+); Xref=Rhea:RHEA:24384, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:29985, ChEBI:CHEBI:30616,

CC ChEBI:CHEBI:58437, ChEBI:CHEBI:456215; EC=6.3.5.1;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02090,
CC ECO:0000256|PIRNR:PIRNR006630};
CC -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; NAD(+) from
CC deamido-NAD(+) (L-Gln route): step 1/1. {ECO:0000256|ARBA:ARBA00005188,
CC ECO:0000256|HAMAP-Rule:MF_02090, ECO:0000256|PIRNR:PIRNR006630}.
CC -!- SIMILARITY: Belongs to the NAD synthetase family.
CC {ECO:0000256|RuleBase:RU003811}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the NAD synthetase
CC family. {ECO:0000256|ARBA:ARBA00007145, ECO:0000256|HAMAP-
CC Rule:MF_02090, ECO:0000256|PIRNR:PIRNR006630}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02090}.
