Mycobacterial Membrane Proteins QcrB and AtpE: Roles in Energetics, Antibiotic Targets, and Associated Mechanisms of Resistance.

Infections caused by mycobacteria are difficult to treat due to their inherent physiology, cellular structure, and intracellular lifestyle. Mycobacterium tuberculosis is a pathogen of global concern as it causes tuberculosis (TB) in humans, which requires 6-9 months of chemotherapy. The situation is further exacerbated in the case of infections caused by drug-resistant strains, which necessitate the prolonged use of agents associated with increased host toxicities.
