2.4.2.30 |
Accepted name: |
NAD+ ADP-ribosyltransferase |
Reaction: |
NAD+ + (ADP-D-ribosyl)n-acceptor = nicotinamide + (ADP-D-ribosyl)n+1-acceptor + H+ |

Other name(s): |
poly(ADP-ribose) synthase; ADP-ribosyltransferase (polymerizing); NAD ADP-ribosyltransferase; PARP; PARP-1; 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 |
Comments: |
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. |
