Localised activity of reverse gyrase at gene regulatory elements

DNA topoisomerases are essential enzymes found in all cells, where they regulate DNA supercoiling. Reverse gyrase (RG) is a unique type of topoisomerase that introduces positive supercoils into DNA an...

Delighted to share our latest preprint on reverse gyrase, a unique topoisomerase found exclusively in thermophiles! www.biorxiv.org/content/10.6...

Reverse gyrase and 3D genome architecture suppress hyperthermophile genome instability arising from horizontal gene transfer

Reverse gyrase (Rgy), a distinctive topoisomerase conserved in all hyperthermophiles, has the unique ability to introduce positive DNA supercoils. It has long been hypothesized that Rgy overwinds geno...
