Protein

Na(+)/H(+) antiporter subunit A1

Gene

mnhA1

Organism
Staphylococcus aureus
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Mnh complex is a Na+Li+/H+ antiporter involved in Na+ and/or Li+ excretion. Na+/H+ antiport consumes a transmembrane electrical potential, and is thus inferred to be electrogenic. Does not transport K+, Ca2+ or Mg2+.

Enzyme regulationi

Na+ extrusion is completely inhibited by the H+ conductor carbonyl cyanide m-chlorophenylhydrazone (CCCP).

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
