Human nicotinate phosphoribosyltransferase (NAPRTase) is localized in the cytoplasm and is involved in
BIOLOG
ical processes such as NAD biosynthetic and metabolic processes, nicotinamide metabolic process, nicotinate nucleotide salvage, response to oxidative stress and water-soluble vitamin metabolic process. It functions by catalyzing the conversion of nicotinic acid (NA) to NA mononucleotide (NaMN) and is essential for NA to increase cellular NAD levels and prevent oxidative stress of the cells. It is a crucial factor in the NAD
+
biosynthesis pathway.
Catalytic activity: Β-nicotinate D-ribonucleotide + diphosphate = nicotinate + 5-phospho-α-D-ribose 1-diphosphate.
