Ion Binding and Selectivity of the Na<sup>+</sup>/H<sup>+</sup> Antiporter MjNhaP1 from Experiment and Simulation Open
Cells employ membrane-embedded antiporter proteins to control their pH, salt concentration, and volume. The large family of cation/proton antiporters is dominated by Na+/H+ antiporters that exchange sodium ions against protons, but homolog…

Mechanism of electroneutral sodium/proton antiporter from transition-path shooting Open
Na + /H + antiporters exchange sodium ions (Na + ) and protons (H + ) on opposite sides of lipid membranes, using the gradient of one ion to drive the uphill transport of the other. The electroneutral Na + /H + antiporter NhaP from archaea…

Redox-coupled quinone dynamics in the respiratory complex I Open
Significance Complex I is the primary energy-converting enzyme of aerobic respiratory chains. By reducing quinone to quinol, this gigantic enzyme pumps protons across its membrane domain, which in turn powers ATP synthesis and active trans…

Accessory NUMM (NDUFS6) subunit harbors a Zn-binding site and is essential for biogenesis of mitochondrial complex I Open
Significance Respiratory complex I is the largest membrane protein complex in mitochondria and has a central function in energy metabolism. Numerous human diseases are linked with complex I dysfunction or assembly defects. The concerted as…
