CC -!- FUNCTION: A type II topoisomerase that negatively supercoils closed
CC circular double-stranded (ds) DNA in an ATP-dependent manner to
CC modulate DNA topology and maintain chromosomes in an underwound state.
CC Negative supercoiling favors strand separation, and DNA replication,
CC transcription, recombination and repair, all of which involve strand
CC separation. Also able to catalyze the interconversion of other
CC topological isomers of dsDNA rings, including catenanes and knotted
CC rings. Type II topoisomerases break and join 2 DNA strands
CC simultaneously in an ATP-dependent manner. {ECO:0000256|HAMAP-
CC Rule:MF_01897}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP-dependent breakage, passage and rejoining of double-
CC stranded DNA.; EC=5.6.2.2; Evidence={ECO:0000256|ARBA:ARBA00000185,
CC ECO:0000256|HAMAP-Rule:MF_01897};
CC -!- SUBUNIT: Heterotetramer, composed of two GyrA and two GyrB chains. In
CC the heterotetramer, GyrA contains the active site tyrosine that forms a
CC transient covalent intermediate with DNA, while GyrB binds cofactors
CC and catalyzes ATP hydrolysis. {ECO:0000256|HAMAP-Rule:MF_01897}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01897}.
CC -!- MISCELLANEOUS: Few gyrases are as efficient as E.coli at forming
CC negative supercoils. Not all organisms have 2 type II topoisomerases;
CC in organisms with a single type II topoisomerase this enzyme also has
CC to decatenate newly replicated chromosomes. {ECO:0000256|HAMAP-
CC Rule:MF_01897}.
CC -!- SIMILARITY: Belongs to the type II topoisomerase GyrA/ParC subunit
CC family. {ECO:0000256|ARBA:ARBA00008263, ECO:0000256|HAMAP-
CC Rule:MF_01897}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
