EspG secretion is key in understanding the virulence of ''mycobacterium tuberculosis''. The specificity of EspG binding affinity to its specific PE-PPE ligand have many contributing factors. The four different EspG proteins found in ''mycobacterium tuberculosis'' have different characteristics that influence binding, where EspG5 binds to the most PE-PPE proteins. Here EspG5 binds to PE25-PPE41 to be excreted in the ESAT-6 pathway. | EspG secretion is key in understanding the virulence of ''mycobacterium tuberculosis''.
