CC   -!- FUNCTION: A type II topoisomerase that negatively supercoils
CC       closed circular double-stranded (ds) DNA in an ATP-dependent
CC       manner to modulate DNA topology and maintain chromosomes in an
CC       underwound state. Negative supercoiling favors strand separation,
CC       and DNA replication, transcription, recombination and repair, all
CC       of which involve strand separation. Also able to catalyze the
CC       interconversion of other topological isomers of dsDNA rings,
CC       including catenanes and knotted rings. Type II topoisomerases
CC       break and join 2 DNA strands simultaneously in an ATP-dependent
CC       manner. {ECO:0000256|HAMAP-Rule:MF_01898}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP-dependent breakage, passage and rejoining of double-
CC         stranded DNA.; EC=5.6.2.3; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_01898, ECO:0000256|SAAS:SAAS01180974};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000256|SAAS:SAAS00924966};
CC   -!- COFACTOR:
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC         Evidence={ECO:0000256|SAAS:SAAS00888357};
CC   -!- SUBUNIT: Heterotetramer, composed of two GyrA and two GyrB chains.
CC       In the heterotetramer, GyrA contains the active site tyrosine that
CC       forms a transient covalent intermediate with DNA, while GyrB binds
CC       cofactors and catalyzes ATP hydrolysis. {ECO:0000256|HAMAP-
CC       Rule:MF_01898}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01898}.
CC   -!- MISCELLANEOUS: Few gyrases are as efficient as E.coli at forming
CC       negative supercoils. Not all organisms have 2 type II
CC       topoisomerases; in organisms with a single type II topoisomerase
CC       this enzyme also has to decatenate newly replicated chromosomes.
CC       {ECO:0000256|HAMAP-Rule:MF_01898}.
CC   -!- SIMILARITY: Belongs to the type II topoisomerase family.
CC       {ECO:0000256|HAMAP-Rule:MF_01898}.
