Specific cleavage of chicken alpha A-globin and human c-Ha-ras genes by two molecular forms of calf thymus topoisomerase I.

I B Bronstein1, I I Gromova, S V Razin.   

Abstract

Two molecular forms of topoisomerase I differing in size and sensitivity to camptothecin were isolated from calf thymus. Mapping of topo I cleavage sites of the cloned chicken alpha A-globin and human c-Ha-ras genes was carried out. Camptothecin was shown to affect site specificity of the topoisomerases.
