ABSTRACT Bacteria perform diverse redox chemistries in the periplasm, cell wall, and extracellular space. Electron transfer for these extracytosolic activities is frequently mediated by proteins with covalently bound flavins, which are attached throu

The Na+-pumping NADH-ubiquinone oxidoreductase (Na+-NQR) is a unique respiratory enzyme found in many pathogenic bacteria. Here, the authors present high-resolution cryo-EM structures of Na+-NQR from V. cholerae with or without a bound inhibitor.

Pseudomonas aeruginosa is a ubiquitous opportunistic pathogen which relies on a highly adaptable metabolism to achieve broad pathogenesis. In one example of this flexibility, to catalyze the NADH:quinone oxidoreductase step of the respiratory chain,

ABSTRACT In bacteria, the respiratory pathways that drive molecular transport and ATP synthesis include a variety of enzyme complexes that utilize different electron donors and acceptors. This property allows them to vary the efficiency of energy con

A ferredoxin:NAD+ oxidoreductase was recently discovered as a redox-driven ion pump in the anaerobic, acetogenic bacterium Acetobacterium woodii. The enzyme is assumed to be encoded by the rnf genes. Since these genes are present in the genomes of ma

The sodium -pumping NADH: ubiquinone oxidoreductase (Na+-NQR) is the main ion pump and the primary entry site for electrons into the respiratory chain of many different types of pathogenic bacteria. This enzymatic complex creates a transmembrane grad

Bacteroides species can use fumarate and oxygen as terminal electron acceptors during cellular respiration. In the human gut, oxygen diffuses from intestinal epithelial cells supplying “nanaerobic” oxygen levels. Many components of the anaerobic

The Na(+)-pumping NADH-ubiquinone (UQ) oxidoreductase (Na(+)-NQR) is present in the respiratory chain of many pathogenic bacteria and is thought to be a promising antibiotic target. Whereas many details of Na(+)-NQR structure and function are known,

Pseudomonas aeruginosa has four Na+/H+ antiporters that interconvert and balance Na+ and H+ gradients across the membrane. These gradients are important for bioenergetics and ionic homeostasis. To understand these transporters, we constructed four st
