PFAM accession number:PF04095
Interpro abstract (IPR041525):

Nicotinate phosphoribosyltransferase ( EC ) is the rate-limiting enzyme that catalyses the first reaction in the NAD salvage synthesis [ (PUBMED:18490451) ]. Members in this family can be split into two further subfamilies represented in IPR006405 and IPR006406 . Members in IPR006405 have a different (longer) spacing of several key motifs and have an additional C-terminal domain of up to 100 residues. However, one argument suggesting that this family represents the same enzyme is that no species has a member of both subfamilies. Another is that the gene encoding this protein is located near other NAD salvage biosynthesis genes in Nostoc and in at least four different Gram-positive bacteria.

Nicotinamide phosphoribosyl transferase (NAMPT) catalyses the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, an intermediate in the biosynthesis of NAD [ (PUBMED:19149599) (PUBMED:19109034) ]. NAMPT is also known as pre-B cell colony-enhancing factor (PBEF) or visfatin.
