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.
  • CATALYTIC ACTIVITY: ATP + nicotinamide ribonucleotide = diphosphate + NAD+.
  • CATALYTIC ACTIVITY: ATP + nicotinate ribonucleotide = diphosphate + deamido-NAD+.
  • COFACTOR: Divalent metal cations. Zinc confers higher activity as compared to magnesium.
  • ENZYME REGULATION: Activity is strongly inhibited by galotannin. Inhibited by P1-(adenosine-5')-P4-(nicotinic-acid-riboside-5')-tetraphosphate (Nap4AD).
  • BIOPHYSICOCHEMICAL PROPERTIES:
    Kinetic parameters:   KM=34 µM for NMN;
    KM=40 µM for ATP;
    KM=937 µM for PPi;
    KM=59 µM for NAD+;
    Vmax=25 µmol/min/mg enzyme for NAD synthesis;
    Vmax=60.5 µmol/min/ug enzyme for NAD+ cleavage;
    Vmax=8.5 µmol/min/ug enzyme for NADH cleavage;
  • PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; NAD(+) from nicotinamide ribonucleotide: step 1/1.
  • SUBUNIT: Homohexamer. Interacts with ADPRT/PARP1.
  • SUBCELLULAR LOCATION: Nucleus.
  • TISSUE SPECIFICITY: Widely expressed with highest levels in skeletal muscle, heart and kidney. Also expressed in the liver pancreas and placenta. Widely expressed throughout the brain.
  • PTM: Phosphorylated.
  • SIMILARITY: Belongs to the eukaryotic NMN adenylyltransferase family.
