Roles of SmeYZ, SbiAB, and SmeDEF Efflux Systems in Iron Homeostasis of Stenotrophomonas maltophilia

open access: yesMicrobiology Spectrum, 2022
Stenotrophomonas maltophilia, a nonfermenting Gram-negative rod, is frequently isolated from the environment and is emerging as a multidrug-resistant global opportunistic pathogen. S.

Coincidence analysis of efflux pumps in the Escherichia coli pangenome

open access: yes, 2023
Global rates of multi-drug resistance continue to rise, posing a significant challenge in the fight against antimicrobial resistance worldwide. Multi-drug efflux pumps are a significant contributor to this burden.

Efflux Pumps and These Inhibitors

open access: yesVNU Journal of Science: Medical and Pharmaceutical Sciences, 2019
 In this era of multi-drug resistance, efflux pump is one of the major problems which is increasingly concerned by scientists. The structure and mechanism activity of the efflux pumps on both bacteria and eurakyotes that are gradually being clarified. Since then, efflux pump inhibitors have also been studied and initially applied in clinic, that makes ...

The MRP family of drug efflux pumps [PDF]

open access: yesOncogene, 2003
The MRP family is comprised of nine related ABC transporters that are able to transport structurally diverse lipophilic anions and function as drug efflux pumps. Investigations of this family have provided insights not only into cellular resistance mechanisms associated with natural product chemotherapeutic agents, antifolates and nucleotide analogs ...

Vibrio cholerae VexH encodes a multiple drug efflux pump that contributes to the production of cholera toxin and the toxin co-regulated pilus. [PDF]

open access: yesPLoS ONE, 2012
The resistance-nodulation-division (RND) efflux systems are ubiquitous transporters that function in antimicrobial resistance. Recent studies showed that RND systems were required for virulence factor production in Vibrio cholerae. The V. cholerae genome

Introduction: Transporters, Porins, and Efflux Pumps [PDF]

open access: yesChemical 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 ...

Investigating functional interplay among Escherichia coli efflux pumps and their contributions to fitness

open access: yes, 2023
Bacterial efflux pumps are conserved active export proteins, many of which can provide multidrug resistance. In diderm bacteria, two efflux pump structural types — single-component efflux pumps and cell envelope-spanning multicomponent systems ...

Fluorescence-Based Flow Sorting in Parallel with Transposon Insertion Site Sequencing Identifies Multidrug Efflux Systems in Acinetobacter baumannii

open access: yesmBio, 2016
Multidrug efflux pumps provide clinically significant levels of drug resistance in a number of Gram-negative hospital-acquired pathogens. These pathogens frequently carry dozens of genes encoding putative multidrug efflux pumps.

Efflux pump-mediated resistance in chemotherapy

open access: yesAnnals of Medical and Health Sciences Research, 2012
Efflux pump mechanisms perform important physiological functions such as prevention of toxin absorption from the gastrointestinal tract, elimination of bile from the hepatocytes, effective functioning of the blood-brain barrier and placental barrier, and renal excretion of drugs.

Determination of efflux activity in Enterococci by Hoechst accumulation assay and the role of zinc oxide nanoparticles in inhibition of this activity

open access: yesBMC Microbiology, 2022
Background Contribution of efflux pumps in development of antimicrobial resistance has been largely addressed in Gram negative and to a much lesser extent in Gram positive bacteria.
