Enzyme Information

2.4.2.-

Pentosyltransferases.

based on mapping to UniProt Q9H2K2

2.4.2.30

NAD(+) ADP-ribosyltransferase.

based on mapping to UniProt Q9H2K2

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.
