DNA cleavage and opening reactions of human topoisomerase IIα are regulated via Mg(2+)-mediated dynamic bending of gate-DNA

Topoisomerase II resolves intrinsic topological problems of double-stranded DNA. As part of its essential cellular functions, the enzyme generates DNA breaks, but the regulation of this potentially dangerous process is not well understood. Here we report single-molecule fluorescence experiments that...
