mrpF

Gene
mrpF
Protein
Na(+)/H(+) antiporter subunit F
Organism
Bacillus subtilis (strain 168)
Length
94 amino acids
Function
Involved in cholate and Na(+) efflux activities, which may be mechanistically coupled. Does not require other Mrp proteins for its own function.
Similarity
Belongs to the CPA3 antiporters (TC 2.A.63) subunit F family.
Mass
10.244 kDa

Gene

Protein
Na(+)/H(+) antiporter subunit F
Organism
Bacillus pseudofirmus (strain OF4)
Length
91 amino acids
Function
Mnh complex is a Na(+)Li(+)/H(+) antiporter involved in Na(+) and/or Li(+) excretion and Na(+) resistance. Na(+)/H(+) antiport consumes a transmembrane electrical potential, and is thus inferred to be electrogenic. Does not transport K(+), Ca(2+) or Mg(2+).
Similarity
Belongs to the CPA3 antiporters (TC 2.A.63) subunit F family.
