General annotation (Comments)

Function

Catalyzes a key step in NAD biosynthesis, transforming deamido-NAD into NAD by a two-step reaction.

Catalytic activity

ATP + deamido-NAD(+) + NH(3) = AMP + diphosphate + NAD(+).

Pathway

Cofactor biosynthesis; NAD(+) biosynthesis; NAD(+) from deamido-NAD(+) (ammonia route): step 1/1.

Subunit structure

Homodimer.

Post-translational modification

May be phosphorylated.

Sequence similarities

Belongs to the NAD synthetase family.
