Protein

DNA gyrase subunit B

Gene

gyrB

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

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.3 PublicationsUniRule annotation

Catalytic activityi

ATP-dependent breakage, passage and rejoining of double-stranded DNA.4 PublicationsUniRule 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+.2 PublicationsUniRule annotation

Enzyme regulationi

Target of two classes of inhibitors, coumarins and quinolones. Coumarins bind to GyrB and are competitive inhibitors with respect to ATP. Quinolones bind DNA gyrase when the enzyme is complexed with DNA and trap the enzyme in a covalent reaction intermediate with DNA.
