Abstract

We characterized a DNA repair system in frog oocytes by comicroinjection of UV-irradiated pBR322 DNA and radiolabeled nucleotides. Repair synthesis was monitored by incorporation of label into recovered pBR322 DNA and by a novel method in which the removal of UV photoproducts was determined from the shift of DNA topoisomers that occurs during gel electrophoresis upon repair of these lesions. We investigated the effects of several drugs in the oocyte system and found that although novobiocin, an inhibitor of topoisomerase II, was an effective inhibitor of repair, VM-26, another inhibitor of topoisomerase II, was not. In addition, the topoisomerase I inhibitor camptothecin had no effect on repair in this system. Finally, circular DNA (either supercoiled or nicked circular) was repaired at least 50 times more rapidly than linear DNA.
