(ADP-ribosyl)hydrolase 1, also termed [Protein ADP-ribosylarginine] hydrolase and protein-Nω-(ADP-D-ribosyl)-L-arginine ADP-ribosylhydrolase (EC3.2.2.19), is an enzyme that in humans is encoded by the ADPRH gene.[1][2][3][4][5] This enzyme is a specific mono(ADP-ribosyl)hydrolase that catalyses the removal of an ADP-ribosyl modification from target arginine residues of protein substrates.[4][6] The chemical reactions can formally be described as follows:
