Natl. Acad. Sci. U.S.A. 97:12176-12181(2000). CC -!- FUNCTION: DNA gyrase negatively supercoils closed circular double- CC stranded DNA in an ATP-dependent manner and also catalyzes the CC interconversion of other topological isomers of double-stranded CC DNA rings, including catenanes and knotted rings (By similarity). CC -!- CATALYTIC ACTIVITY: ATP-dependent breakage, passage and rejoining CC of double-stranded DNA. CC -!- SUBUNIT: Made up of two chains. The A chain is responsible for DNA CC breakage and rejoining; the B chain catalyzes ATP hydrolysis. The CC enzyme forms an A2B2 tetramer (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the topoisomerase GyrA/ParC subunit family.
