Mycobacterium tuberculosis cell wall synthesis pathway

The *Mycobacterium tuberculosis* cell wall synthesis pathway comprises numerous enzymes responsible for assembling a unique, lipid-rich, multi-layered envelope. This cell wall is made up of three main components: a peptidoglycan layer, an arabinogalactan polysaccharide, and a mycolic acid outer layer, with additional complex glycolipids and free lipids[2][3][4][6][7]. The cell wall’s structure furnishes *M. tuberculosis* with resilience to environmental stresses, resistance to both host immunity and antibiotics, and is directly implicated in the organism’s virulence and persistence. Because of its essential role in bacterial survival and pathogenesis, enzymes and processes in this pathway are the most widely exploited targets for both first-line and novel anti-tuberculosis drugs. However, drug resistance and challenges in drug delivery due to the impermeable barrier remain major obstacles to effective therapy[4][3][7].
