DESCRIPTION
Also known as GYRB_ENTFA, gyrB. 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. 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.
