Protein attributes
| Sequence length | 327 AA. |
| Sequence status | Fragment. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
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. HAMAP-Rule MF_01897 |
| Catalytic activity | ATP-dependent breakage, passage and rejoining of double-stranded DNA. HAMAP-Rule MF_01897 |
| Subunit structure | Heterotetramer, composed of two GyrA and two GyrB chains. Within the heterotetramer, GyrA contains the active site tyrosine that forms a covalent intermediate with the DNA, while GyrB contributes the cofactor binding sites and catalyzes ATP hydrolysis By similarity. |
| Subcellular location | Cytoplasm Potential HAMAP-Rule MF_01897. |
| Post-translational modification | This protein undergoes a protein self splicing that involves a post-translational excision of the intervening region (intein) followed by peptide ligation. HAMAP-Rule MF_01897 |
| Sequence similarities | Belongs to the topoisomerase GyrA/ParC subunit family. |
