Expression of the Fluoroquinolones Efflux Pump Genes acrA and mdfA in Urinary Escherichia coli Isolates [PDF]
Polish Journal of Microbiology, 2017 Escherichia coli is one of the most frequent causes of urinary tract infections. Efflux system overexpression is reported to contribute to E. coli resistance to several antibiotics. Our aim in this study was to investigate the relation between antibiotic

Conformational Dynamics of AcrA Govern Multidrug Efflux Pump Assembly [PDF]
ACS Infectious Diseases, 2019 Multidrug efflux pumps of pathogenic, Gram-negative bacteria comprise an innate resistance mechanism and are key contributors to the emerging global pandemic of antibiotic resistance. Several increasingly detailed cryo-electron microscopy maps have been resolved of an entire efflux pump complex, AcrAB-TolC, resulting in atomistic structural models ...

Circulation: Cardiovascular Interventions, 2019 BACKGROUND: Transradial intervention (TRI) may impair digital perfusion with hand dysfunction as a result. However, the effect of TRI on digital perfusion has never been investigated, including the influence of variations of the collateral arterial network and the effect on hand dysfunction.

Efflux Pump-Binding 4(3-Aminocyclobutyl)Pyrimidin-2-Amines Are Colloidal Aggregators
Biomolecules, 2023 Efflux pumps are a relevant factor in antimicrobial resistance. In E. coli, the tripartite efflux pump AcrAB-TolC removes a chemically diverse set of antibiotics from the bacterium.

Defining the RND-binding residues of AcrA
Access Microbiology, 2020 The resistance-nodulation-division (RND) family of efflux pumps confer clinically relevant antibiotic resistance in Gram-negative bacteria, such as Salmonella enterica. RND pumps, including AcrB, are organized as tri-partite systems, consisting of an inner membrane RND pump, a periplasmic adaptor protein (PAP) and an outer membrane channel. Previously,
