Using cellular fitness to map the structure and function of a major facilitator superfamily effluxer. [PDF]
, 2017 The major facilitator superfamily (MFS) effluxers are prominent mediators of antimicrobial resistance. The biochemical characterization of MFS proteins is hindered by their complex membrane environment that makes in vitro biochemical analysis challenging.

A cell-based infection assay identifies efflux pump modulators that reduce bacterial intracellular load. [PDF]
PLoS Pathogens, 2018 Bacterial efflux pumps transport small molecules from the cytoplasm or periplasm outside the cell. Efflux pump activity is typically increased in multi-drug resistant (MDR) pathogens; chemicals that inhibit efflux pumps may have potential for antibiotic ...

Efflux Pump Inhibitors against Nontuberculous Mycobacteria [PDF]
International Journal of Molecular Sciences, 2020 Over the last years, nontuberculous mycobacteria (NTM) have emerged as important human pathogens. Infections caused by NTM are often difficult to treat due to an intrinsic multidrug resistance for the presence of a lipid-rich outer membrane, thus encouraging an urgent need for the development of new drugs for the treatment of mycobacterial infections ...

Introduction: Transporters, Porins, and Efflux Pumps [PDF]
Chemical Reviews, 2021 All living cells are surrounded by lipidic membranes that separate metabolic and macromolecular biosynthetic processes from external environments. Biological membranes vary dramatically in their composition and structures and are optimized by mega-annum of evolution to effectively carry out diverse biological functions including energy production ...

The Impact of Triclosan on the Spread of Antibiotic Resistance in the Environment [PDF]
, 2015 Triclosan (TCS) is a commonly used antimicrobial agent that enters wastewater treatment plants (WWTPs) and the environment. An estimated 1.1 × 105 to 4.2 × 105 kg of TCS are discharged from these WWTPs per year in the United States.

The Varied Role of Efflux Pumps of the MFS Family in the Interplay of Bacteria with Animal and Plant Cells [PDF]
, 2019 Efflux pumps represent an important and large group of transporter proteins found in all organisms. The importance of efflux pumps resides in their ability to extrude a wide range of antibiotics, resulting in the emergence of multidrug resistance in many

Biochemistry of Bacterial Multidrug Efflux Pumps [PDF]
International Journal of Molecular Sciences, 2012 Bacterial pathogens that are multi-drug resistant compromise the effectiveness of treatment when they are the causative agents of infectious disease. These multi-drug resistance mechanisms allow bacteria to survive in the presence of clinically useful antimicrobial agents, thus reducing the efficacy of chemotherapy towards infectious disease ...
