The P55 drug efflux pump (Rv141Oc) (extrudes drugs including rifampicin and clifazimine, first- and second-line anti-tuberculosis drugs. CCCP and valinomycin inhibited drug resistance) (Ramón-García et al., 2009).  P55 also exports malachite green, ethidium bromide, isoniazid and ethambutol (Bianco et al. 2011).  Functions together with the outer membrane lipoprotein porin, LprG, also called P27 and Lpp-27 (Bianco et al. 2011; Farrow and Rubin 2008).  Required together with LprG for normal colony morphology and sliding motility, possibly due to alterred cell wall composition (Farrow and Rubin 2008).  Required together with LprG for normal colony morphology and sliding motility, possibly due to alterred cell wall composition (Farrow and Rubin 2008).
