Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD). ATP + H(+) + nicotinate beta-D-ribonucleotide = deamido-NAD(+) + diphosphate Activity is susceptible to product inhibition. Cofactor biosynthesis; NAD(+) biosynthesis; deamido-NAD(+) from nicotinate D-ribonucleotide: step 1/1. Belongs to the NadD family.
