    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.
