Enzyme Information
| 2.4.2.- | Pentosyltransferases. based on mapping to UniProt P09874 | 
| 2.4.2.30 | NAD(+) ADP-ribosyltransferase. based on mapping to UniProt P09874 NAD(+) + (ADP-D-ribosyl)(n)-acceptor = nicotinamide + (ADP-D- ribosyl)(n+1)-acceptor. -!- 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. |
