Enzyme
DNA gyrase
Definitions related to dna gyrase:
-
A bacterial DNA topoisomerase II that catalyzes ATP-dependent breakage of both strands of DNA, passage of the unbroken strands through the breaks, and rejoining of the broken strands. Gyrase binds to DNA as a heterotetramer consisting of two A and two B subunits. In the presence of ATP, gyrase is able to convert the relaxed circular DNA duplex into a superhelix. In the absence of ATP, supercoiled DNA is relaxed by DNA gyrase.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
Catalyzes the twisting of relaxed, circular DNA into a super coiled state.CRISP ThesaurusNational Institutes of Health, 2006
