In enzymology a NAD(P)+-protein-arginine ADP-ribosyltransferase (EC 2.4.2.31) is an enzyme that catalyzes the chemical reaction using nicotinamide adenine dinucleotideNAD+ + protein L-arginine nicotinamide + Nomega-(ADP-D-ribosyl)-protein-L-arginine NADP+ + protein L-arginine nicotinamide + Nomega-[(2′-phospho-ADP)-D-ribosyl]-protein-L-arginineas well as the corresponding reaction using nicotinamide adenine dinucleotide phosphateNADP+ + protein L-arginine nicotinamide + Nomega-(ADP-D-ribosyl)-protein-L-arginine NADP+ + protein L-arginine nicotinamide + Nomega-[(2′-phospho-ADP)-D-ribosyl]-protein-L-arginineThus the two substrates of this enzyme are NAD+ (or NADP+) and protein L-arginine whereas its two products are nicotinamide and Nomega-(ADP-D-ribosyl)-protein-L-arginine (or Nomega-[(2′-phospho-ADP)-D-ribosyl]-protein-L-arginine respectively).This enzyme belongs to the family of glycosyltransferases specifically the pentosyltransferases.
