NAD+-dinitrogen-reductase ADP-D-ribosyltransferase

From Wikipedia, the free encyclopedia

In enzymology, a NAD+-dinitrogen-reductase ADP-D-ribosyltransferase (EC 2.4.2.37) is an enzyme that catalyzes the chemical reaction

NAD⁺ + [dinitrogen reductase] $\rightleftharpoons$ nicotinamide + ADP-D-ribosyl-[dinitrogen reductase]

Thus, the two substrates of this enzyme are NAD⁺ and [[[dinitrogen reductase]]], whereas its two products are nicotinamide and [[ADP-D-ribosyl-[dinitrogen reductase]]].

This enzyme belongs to the family of glycosyltransferases, specifically the pentosyltransferases. The systematic name of this enzyme class is NAD+:[dinitrogen reductase] (ADP-D-ribosyl)transferase. Other names in common use include NAD-azoferredoxin (ADPribose)transferase, and NAD-dinitrogen-reductase ADP-D-ribosyltransferase.
