Protein attributes

Sequence length	808 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	DNA gyrase negatively supercoils closed circular double-stranded DNA in an ATP-dependent manner and also catalyzes the interconversion of other topological isomers of double-stranded DNA rings, including catenanes and knotted rings By similarity. RuleBase RU003363 HAMAP MF_01898
Catalytic activity	ATP-dependent breakage, passage and rejoining of double-stranded DNA. SAAS SAAS002288 RuleBase RU003363 HAMAP MF_01898
Subunit structure	Made up of two chains. The A chain is responsible for DNA breakage and rejoining; the B chain catalyzes ATP hydrolysis. The enzyme forms an A2B2 tetramer By similarity. HAMAP MF_01898
Subcellular location	Cytoplasm By similarity HAMAP MF_01898.
Sequence similarities	Belongs to the type II topoisomerase family. HAMAP MF_01898 RuleBase RU000380
