Infect. Dis. 170:479-483(1994). 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. CC -!- CATALYTIC ACTIVITY: ATP-dependent breakage, passage and rejoining CC of double-stranded DNA. CC -!- SUBUNIT: Heterotetramer, composed of two GyrA and two GyrB chains. CC Within the heterotetramer, GyrA contains the active site tyrosine CC that forms a covalent intermediate with the DNA, while GyrB CC contributes the cofactor binding sites and catalyzes ATP CC hydrolysis (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (Potential). CC -!- MISCELLANEOUS: When the enzyme transiently cleaves DNA a CC phosphotyrosine bond is formed between the gyrA and DNA. CC -!- SIMILARITY: Belongs to the topoisomerase GyrA/ParC subunit family.
