Title Poly(ADP-ribosylation) of DNA topoisomerase I from calf thymus
Date 1984
Description We demonstrate that the activity of the major DNA topoisomerase I from calf thymus is severely inhibited after modification by purified poly(ADP-ribose) synthetase. Polymeric chains of poly(ADP-ribose) are covalently attached to DNA topoisomerase I. These observations with highly purified enzymes suggest that poly(ADP-ribosylation) may be a cellular mechanism for modulating DNA topoisomerase I activity in response to the state of DNA in the nucleus.
