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 DNA
CC rings, including catenanes and knotted rings. {ECO:0000255|HAMAP-
CC Rule:MF_01898, ECO:0000269|PubMed:23352267,
CC ECO:0000269|PubMed:24386374}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP-dependent breakage, passage and rejoining of double-
CC stranded DNA.; EC=5.6.2.2; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01898};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01898};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01898};
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01898};
CC Note=Binds two Mg(2+) per subunit. The magnesium ions form salt bridges
CC with both the protein and the DNA. Can also accept other divalent metal
CC cations, such as Mn(2+) or Ca(2+). {ECO:0000255|HAMAP-Rule:MF_01898};
CC -!- ACTIVITY REGULATION: Pyrrolopyrimidines inhibit both GyrB and its
CC paralog in topoisomerase IV (parE) (PubMed:23352267).
CC {ECO:0000269|PubMed:23352267, ECO:0000269|PubMed:24386374}.
CC -!- SUBUNIT: Heterotetramer, composed of two GyrA and two GyrB chains.
CC Within the heterotetramer, GyrA contains the active site tyrosine that
CC forms a covalent intermediate with the DNA, while GyrB contributes the
CC cofactor binding sites and catalyzes ATP hydrolysis.
CC {ECO:0000255|HAMAP-Rule:MF_01898}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01898}.
CC -!- SIMILARITY: Belongs to the type II topoisomerase family.
CC {ECO:0000255|HAMAP-Rule:MF_01898}.
