Cell Cycle–coupled Relocation of Types I and II Topoisomerases and Modulation of Catalytic Enzyme Activities

We visualized DNA topoisomerases in A431 cells and isolated chromosomes by isoenzyme-selective immunofluorescence microscopy. In interphase, topoisomerase I mainly had a homogeneous nuclear distribution. 10–15% of the cells exhibited granular patterns, 30% showed bright intranucleolar patches. Topoi...
