Proteomic Time-Course Investigation into the Effects of Exposure of Mycobacterium smegmatis to Sub-Lethal Dose of Rifampicin

Drug susceptible Mycobacterium smegmatis (Mc2-155) was exposed to a sub-MIC concentration of antimycobacterial drug Rifampicin (treated) or DMSO (control). Cells were harvested at 30, 255 and 300 minutes post-exposure and the proteome at each time analysed using LC-MS/MS on a Thermo Q-Exactive.
