Crystal Structure of Mouse Nicotinamide Phosphoribosyltransferase/Visfatin/Pre-B Cell Colony Enhancing Factor 1
Overview
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.
About this Structure
2H3B is a Single protein structure of sequence from Mus musculus with as ligand. Active as Nicotinamide phosphoribosyltransferase, with EC number 2.4.2.12 Full crystallographic information is available from OCA.
