MmpL transporters export substrates that are important for virulence and pathogenicity. MmpL proteins and membrane-associated transport partners, exported substrates, and contributions to virulence/pathogenicity of the mature exported substrates. TMM/TDM—trehalose mono/di-mycolate; AGP—arabinogalactan/peptidoglycan complex; (c)MBT—(carboxy)mycobactin; PDIM—phthiocerol dimycocerosate; PAMP—pathogen-associated molecular pattern; PRR—pattern recognition receptor; DAT/PAT—di/poly-acyl trehalose; LC-TAG—long-chain triacylglycerol; and MWE—mycolate wax ester.
