Chromatin regulates DNA torsional energy via topoisomerase II-mediated relaxation of positive supercoils

Eukaryotic topoisomerases I (topo I) and II (topo II) relax the positive (+) and negative (−) DNA torsional stress (TS) generated ahead and behind the transcription machinery. It is unknown how this DNA relaxation activity is regulated and whether (+) and (−)TS are reduced at similar rates. Here, we...
