Crystal Structure of Mouse Nicotinamide Phosphoribosyltransferase/Visfatin/Pre-B Cell Colony Enhancing Factor 1
Structural highlights
FunctionNAMPT_MOUSE 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.[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedNicotinamide 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.
