Gyrase (Gyr) is a type of topoisomerase II in prokaryotes which unwinds double stranded DNA. The DNA Gyr cutting allows the formation of a negative DNA supercoil which enables replication of DNA. Gyr consists of 2 subunits: GyrA and GyrB. Reverse gyrase (Top-RG) is a type of topoisomerase I which catalyses the formation of positive DNA supercoil. [1]
