01
Overview
Mycobacterium tuberculosis membrane transport refers to the collection of specialized systems and proteins that facilitate the movement of nutrients, metabolites, ions, and drugs across the unique and highly impermeable cell envelope of Mtb. This process is critical for bacterial survival, adaptation within host environments, drug resistance, and pathogenesis. Key components include PE/PPE family proteins involved in nutrient uptake (e.g., PPE51 for propionamide, glucose, glycerol; PE15/PPE20 for calcium), MmpL family lipid transporters (e.g., for TMM, PDIMs), and efflux pumps that mediate drug resistance. Due to their essential roles and contribution to drug resistance, these transport systems represent promising targets for novel anti-TB therapeutics.
