  • Target

    • RelevanceDNA Gyrase B belongs to the type II topoisomerase family. 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. It is 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.

      Thank you for your enquiry. ab75592 and ab75593 are monclonal antibodies specific to different E coli gyrase protein domains so I'm not sure whether they will react. We haven't tested them against S. aureus gyrase. We have two polyclonal antibodies ...
