Poly(ADP-ribose) Polymerases

Nuclear ADP Ribose Transferases; Nuclear ADP-Ribosyltransferase; Nuclear ADPRT; Nuclear Adenosine Diphosphoribosyltransferase; Nuclear NAD+ ADP-Ribosyltransferase; PARP Polymerase; Poly ADP Ribose Transferase; Poly ADP-Ribose Synthase
Enzymes that catalyze the transfer of multiple ADP-RIBOSE groups from nicotinamide-adenine dinucleotide (NAD) onto protein targets, thus building up a linear or branched homopolymer of repeating ADP-ribose units i.e., POLY ADENOSINE DIPHOSPHATE RIBOSE.
