Protein
Nicotinamide mononucleotide adenylyltransferase 1
Gene
Nmnat1, D4Cole1e, Nmnat
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

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+ By similarity. Protects against axonal degeneration following mechanical or toxic insults. Delays axonal degeneration after axotomy. Results in a >10-fold increase in intact neurites 72 hours after injury.2 Publications

Catalytic activityi

ATP + nicotinamide ribonucleotide = diphosphate + NAD+.By similarity
ATP + beta-nicotinate-D-ribonucleotide = diphosphate + deamido-NAD+.

Cofactori

Divalent metal cations. Zinc confers higher activity than magnesium By similarity.

Enzyme regulationi

Activity is strongly inhibited by galotannin. Inhibited by P1-(adenosine-5')-P4-(nicotinic-acid-riboside-5')-tetraphosphate (Nap4AD) By similarity.

Miscellaneousi

Miscellaneous

In strain C57BL/Ola, an 85 kb region on chromosome 4 containing Nmnat1 and Ube4b is triplicated. The N-terminal 70 residues of Ube4b becomes linked to the complete Nmnat1 protein and encodes a fusion protein located in the nucleus which is responsible for the Wallerian degeneration slow (Wlds) phenotype characterized by delayed Wallerian degeneration of injured axons.
