Protein attributes

Sequence length	863 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. SAAS SAAS006691 HAMAP MF_01897
Catalytic activity	ATP-dependent breakage, passage and rejoining of double-stranded DNA. SAAS SAAS006691 HAMAP MF_01897
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_01897
Subcellular location	Cytoplasm By similarity SAAS SAAS006691 HAMAP MF_01897.
Sequence similarities	Belongs to the topoisomerase GyrA/ParC subunit family. HAMAP MF_01897
