Protein

DNA gyrase subunit B

Gene

gyrB

Organism
Nocardia farcinica (strain IFM 10152)
Status
Unreviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

ATP-dependent breakage, passage and rejoining of double-stranded DNA.UniRule annotationSAAS annotation

Cofactori

Magnesium. Binds two Mg2+ per subunit. The magnesium ions form salt bridges with both the protein and the DNA. Can also accept other divalent metal cations, such as Mn2+ and Ca2+.UniRule annotation

Interactioni

Subunit structurei

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.UniRule annotation
