Abstract
Mycobacterium tuberculosis DNA gyrase, a nanomachine involved in the regulation of DNA topology, is the only type II topoisomerase present in this organism and hence is the sole target of fluoroquinolones in the treatment of tuberculosis. The ATPase domain provides the energy required for catalysis by ATP hydrolysis. Two constructs corresponding to this 43 kDa domain, Mtb-GyrB47(C1) and Mtb-GyrB47(C2), have been overproduced, purified and crystallized. Diffraction data were collected from three crystal forms. The crystals belonged to space groups P1 and P21 and diffracted to resolutions of 2.9 and 3.3 Å, respectively.
