General annotation (Comments)

Function	Catalyzes the formation of NAD+ from nicotinamide mononucleotide (NMN) and ATP. Can also use the deamidated form; nicotinic acid mononucleotide (NaMN) as substrate with the same efficiency. Can use triazofurin monophosphate (TrMP) as substrate. Also catalyzes the reverse reaction, i.e. the pyrophosphorolytic cleavage of NAD+. For the pyrophosphorolytic activity, prefers NAD+ and NAAD as substrates and degrades NADH, nicotinic acid adenine dinucleotide phosphate (NHD) and nicotinamide guanine dinucleotide (NGD) less effectively. Fails to cleave phosphorylated dinucleotides NADP+, NADPH and NAADP+. Protects against axonal degeneration following mechanical or toxic insults By similarity.
Catalytic activity	ATP + nicotinamide ribonucleotide = diphosphate + NAD+. ATP + nicotinate ribonucleotide = diphosphate + deamido-NAD+.
Cofactor	Divalent metal cations. Zinc confers higher activity than magnesium By similarity.
Enzyme regulation	Activity is strongly inhibited by galotannin. Inhibited by P1-(adenosine-5')-P4-(nicotinic-acid-riboside-5')-tetraphosphate (Nap4AD) By similarity.
Pathway	Cofactor biosynthesis; NAD(+) biosynthesis; NAD(+) from nicotinamide D-ribonucleotide: step 1/1.
Subunit structure	Homohexamer. Interacts with ADPRT/PARP1 By similarity.
Subcellular location	Nucleus By similarity.
Post-translational modification	Phosphorylated By similarity.
Sequence similarities	Belongs to the eukaryotic NMN adenylyltransferase family.
