Taxonomic identifier

336407 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rickettsiales › Rickettsiaceae › Rickettsieae › Rickettsia

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 By similarity.
Catalytic activity	ATP-dependent breakage, passage and rejoining of double-stranded DNA.
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.
Sequence similarities	Belongs to the topoisomerase gyrA/parC subunit family.
