Enzyme Information

2.4.2.-
Pentosyltransferases.
based on mapping to UniProt Q9UGN5
2.4.2.30
NAD(+) ADP-ribosyltransferase.
based on mapping to UniProt Q9UGN5
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.
