A mutation in Na(+)-NQR uncouples electron flow from Na(+) translocation in the presence of K(+).

Biochemistry - 20 Jan 2015

Shea Michael E, Mezic Katherine G, Juárez Oscar, Barquera Blanca

Abstract excerpt

The sodium-pumping NADH:ubiquinone oxidoreductase (Na(+)-NQR) is a bacterial respiratory enzyme that obtains energy from the redox reaction between NADH and ubiquinone and uses this energy to create an electrochemical Na(+) gradient across the cell membrane. A number of acidic residues in transmembrane helices have been shown to be important for Na(+) translocation. One of these, Asp-397 in the NqrB subunit, is a...
