Protein Type Enzyme
Biological Properties
General Function Involved in nicotinate phosphoribosyltransferase activity
Specific Function Catalyzes the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, an intermediate in the biosynthesis of NAD. It is the rate limiting component in the mammalian NAD biosynthesis pathway (By similarity).
