WebADP ribosyltransferase is required for cellular repair. Inhibitors of this enzyme potentiate the lethal effects of noxious agents. During repair, NAD+ is consumed and the NAD+ content of the cell decreases. Concomitantly, nuclear proteins are ADP-ribosylated. WebAug 18, 2014 · Poly [ADP-ribose] polymerase 1 (PARP-1) is a highly abundant chromatin-associated enzyme. It catalyzes the NAD +-dependent polymerization of long chains of poly-ADP ribose (PAR) onto itself in response to DNA damage and other cues.More recently, the enzymatic activity of PARP-1 has also been implicated in the regulation of gene expression.
