ENZYME entry: EC 2.4.2.30

Accepted Name
NAD(+) ADP-ribosyltransferase.
Alternative Name(s)
ADP-ribosyltransferase (polymerizing).
Poly(adenosine diphosphate ribose) polymerase.
Poly(ADP-ribose) synthetase.
Poly(ADP-ribose)polymerase.
Reaction catalysed
NAD(+) + (ADP-D-ribosyl)(n)-acceptor <=> nicotinamide + (ADP-D-ribosyl)(n+1)-acceptor
Comment(s)
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.
