title: An assay for the detection of bacterial DNA gyrase inhibitors.
abstract: In summary, we have developed a sensitive detection system for inhibitors of bacterial DNA gyrase. The use of B. subtilis as the host organism confers the advantage that it is sensitive to both gyrase subunit A and B inhibitors, whereas E. coli is relatively insensitive to B subunit inhibitors in vivo. Using this assay, we identified a new DNA gyrase inhibitor with a novel structure.
