IntEnz Enzyme Nomenclature


Accepted name:
NAD+ ADP-ribosyltransferase
Other names:
ADP-ribosyltransferase (polymerizing)
poly(ADP-ribose) synthase
poly(ADP-ribose) synthetase
poly(adenosine diphosphate ribose) polymerase
NAD+:poly(adenine-diphosphate-D-ribosyl)-acceptor ADP-D-ribosyl-transferase [incorrect]
NAD+:poly(adenosine-diphosphate-D-ribosyl)-acceptor ADP-D-ribosyl-transferase
Systematic name:
NAD+:poly(ADP-D-ribosyl)-acceptor ADP-D-ribosyl-transferase



The ADP-D-ribosyl group of NAD+ is transferred to an acceptor carboxy group on a histone or the enzyme itself, and further ADP-ribosyl groups are transferred to the 2'-position of the terminal adenosine moiety, building up a polymer with an average chain length of 20-30 units.
