Figure 5: ESS controls the secretion of EsxA and EsxB proteins in CA-SA ST398.

Equal amounts of secreted proteins from RJ-ST398 wild-type and essB deletion strains were separated by 12% SDS-PAGE and in-gel digested by trypsin before LC-MS/MS analysis. Peaks of peptides derived from EsxA (AQGEIAANWEGQAFSR) and EsxB (LQDAVNSAQTIIEDFNSEK) are shown.
