NADH:ubiquinone oxidoreductase, Na(+)-translocating, B subunit
This model represents the NqrB subunit of the six-protein, Na(+)-pumping NADH-quinone reductase of a number of marine and pathogenic Gram-negative bacteria. This oxidoreductase complex functions primarily as a sodium ion pump. [Transport and binding proteins, Cations and iron carrying compounds]
