Protein attributes
| Sequence length | 905 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. HAMAP MF_01897 |
| Catalytic activity | ATP-dependent breakage, passage and rejoining of double-stranded DNA. 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. |
| Subcellular location | Cytoplasm Potential HAMAP MF_01897. |
| Sequence similarities | Belongs to the topoisomerase GyrA/ParC subunit family. |
