Protein attributes

Sequence length	905 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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.
