CC   -!- FUNCTION: Catalyzes the ATP-dependent amidation of deamido-NAD to form
CC       NAD. Uses ammonia as a nitrogen source. {ECO:0000255|HAMAP-
CC       Rule:MF_00193}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=deamido-NAD(+) + NH4(+) + ATP = AMP + diphosphate + NAD(+) +
CC         H(+); Xref=Rhea:RHEA:21188, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:57540,
CC         ChEBI:CHEBI:58437, ChEBI:CHEBI:456215; EC=6.3.1.5;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00193};
CC   -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; NAD(+) from
CC       deamido-NAD(+) (ammonia route): step 1/1. {ECO:0000255|HAMAP-
CC       Rule:MF_00193}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00193}.
CC   -!- SIMILARITY: Belongs to the NAD synthetase family. {ECO:0000255|HAMAP-
CC       Rule:MF_00193}.
