  • Title: Major facilitator superfamily efflux pumps in human pathogens: Role in multidrug resistance and beyond.
    Author: Lekshmi M, Ortiz-Alegria A, Kumar S, Varela MF.
    Journal: Curr Res Microb Sci; 2024; 7():100248. PubMed ID: 38974671.
    Abstract:
    The major facilitator superfamily (MFS) of proteins constitutes a large group of related solute transporters found across all known living taxa of organisms. The transporters of the MFS contain an extremely diverse array of substrates, including ions, molecules of intermediary metabolism, and structurally different antimicrobial agents. First discovered over 30 years ago, the MFS represents an important collection of integral membrane transporters. Bacterial microorganisms expressing multidrug efflux pumps belonging to the MFS are considered serious pathogens, accounting for alarming morbidity and mortality numbers annually. This review article considers recent advances in the structure-function relationships, the transport mechanism, and modulation of MFS multidrug efflux pumps within the context of drug resistance mechanisms of bacterial pathogens of public health concerns.
