EC=5.99.1.3

Gene names

Name:

gyrB

Organism

Acinetobacter lwoffii

Taxonomic identifier

28090 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Pseudomonadales › Moraxellaceae › Acinetobacter

Protein attributes

Sequence length	390 AA.
Sequence status	Fragment.
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_01898
Catalytic activity	ATP-dependent breakage, passage and rejoining of double-stranded DNA. HAMAP MF_01898
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_01898.
Sequence similarities	Belongs to the type II topoisomerase family.
