Protein Family Models

This is a family of integral membrane proteins including Rhodobacter-specific nitrogen fixation (rnf) proteins RnfA and RnfE [1] and Na+-translocating NADH:ubiquinone oxidoreductase (Na+-NQR) subunits NqrD and NqrE.

NADH:ubiquinone reductase (Na(+)-transporting) subunit E (NqrE) is a component of the NQR complex, which catalyzes the reduction of ubiquinone-1 to ubiquinol by two successive reactions, coupled with the transport of Na(+) ions from the cytoplasm to the periplasm

This HMM represents the NqrE 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 [1].
