Popis: GSK2251052 is a broad-spectrum antibacterial inhibitor of leucyl tRNA-synthetase (LeuRS) that has been evaluated in Phase II clinical trials. Here we report the identification of a clinical isolate of Staphylococcus aureus that exhibits reduced susceptibility to GSK2251052 without prior exposure to the compound, and demonstrate that this phenotype is attributable to a single amino acid polymorphism (P329) within the editing domain of LeuRS.
