Nicotinamide phosphoribosyltransferase (Nampt) synthesizes nicotinamide, mononucleotide (NMN) from nicotinamide in a mammalian NAD+ biosynthetic, pathway and is required for SirT1 activity in vivo. Nampt has also been, presumed to be a cytokine (PBEF) or a hormone (visfatin). The crystal, structure of Nampt in the presence and absence of NMN shows that Nampt is, a dimeric type II phosphoribosyltransferase and provides insights into the, enzymatic mechanism.
