Poly(ADP-ribosyl)ation of DNA polymerase beta in vitro
Biochemical and Biophysical Research Communications
|October 30, 1986
Abstract:
DNA polymerase beta purified from bovine thymus is markedly inhibited when incubated in a reconstituted poly(ADP-ribosyl)ating reaction system. Analyses of the reaction product synthesized in this system by SDS-polyacrylamide gel electrophoresis and subsequent fluorography of the gel indicated that ADP-ribose is covalently attached to DNA polymerase beta molecule (Mr = 44,000).
