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 By similarity. HAMAP-Rule MF_01897

Sequence similarities

Belongs to the topoisomerase GyrA/ParC subunit family.

Contains 1 DOD-type homing endonuclease domain.
