Description
β-NMN is an intermediate in the nicotinamide phosphoribosyltransferase (NAMPT)-catalyzed biosynthesis of nicotinamide adenine dinucleotide (NAD+). NAMPT mediates the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to produce β-NMN. β-NMN adenyltransferase subsequently converts β-NMN to NAD+.
