Increasing resistance to every major class of antibiotics and a dearth of novel classes of antibacterial agents in development pipelines has created a dwindling reservoir of treatment options for serious bacterial infections. The bacterial type IIA topoisomerases, DNA gyrase and topoisomerase IV, are validated antibacterial drug targets with multiple(More)
The leaky heme mutants G204, G216, and G214 are shown to accumulate exogenous sterols. Unlike hem mutants which have complete blocks in the heme pathway, these strains do not require ergosterol, methionine, or unsaturated fatty acids for growth. The addition of aminolevulinic acid to the growth medium inhibited sterol uptake in G204 96% but had only a(More)
