== Function ==
[https://www.uniprot.org/uniprot/GYRB_STAAN GYRB_STAAN] 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 (By similarity).

== Publication Abstract from PubMed ==
During the course of our research on the lead optimisation of the NBTI (Novel Bacterial Type II Topoisomerase Inhibitors) class of antibacterials, we discovered a series of tricyclic compounds that showed good Gram-positive and Gram-negative potency. Herein we will discuss the various subunits that were investigated in this series and report advanced studies on compound 1 (GSK945237) which demonstrates good PK and in vivo efficacy properties.

Novel tricyclics (e.g., GSK945237) as potent inhibitors of bacterial type IIA topoisomerases.,Miles TJ, Hennessy AJ, Bax B, Brooks G, Brown BS, Brown P, Cailleau N, Chen D, Dabbs S, Davies DT, Esken JM, Giordano I, Hoover JL, Jones GE, Kusalakumari Sukmar SK, Markwell RE, Minthorn EA, Rittenhouse S, Gwynn MN, Pearson ND Bioorg Med Chem Lett. 2016 Mar 31. pii: S0960-894X(16)30338-9. doi:, 10.1016/j.bmcl.2016.03.106.
