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 SO4 as ligand. Active as Nicotinamide phosphoribosyltransferase, with EC number 2.4.2.12 Full crystallographic information is available from OCA.
