Gyrase inverse
WebJul 10, 2014 · Reverse gyrases are topoisomerases that introduce positive supercoils into DNA in an ATP-dependent reaction. They consist of a helicase domain and a topoisomerase domain that closely cooperate in catalysis. The mechanism of the functional cooperation of these domains has remained elusive. WebGyrase has multiple roles in DNA replication, recombination, and transcription. Its participation in replication and recombination is briefly summarized here; the complex …
