comments
DNA gyrase is a prokaryotic topoisomerase type II, which relaxes supercoiled DNA. This protein is A subunit of DNA-gyrase, which catalyzes DNA breakage and religation. The B subunit of this enzyme catalyzes hydrolysis of ATP. (see M00213 in EzCatDB).
According to the literature [19], this A subunit of the enzyme seems to catalyzes the DNA breakage in cooperation with the C-terminal domain of the B subunit.
