Identification
Name: Na(+)/H(+) antiporter nhaB
Synonyms:
  • Sodium/proton antiporter nhaB
Gene Name: nhaB
Enzyme Class: Not Available
Biological Properties
General Function: Involved in sodium:hydrogen antiporter activity
Specific Function: Na(+)/H(+) antiporter that extrudes sodium in exchange for external protons. Catalyzes the exchange of 3 H(+) per 2 Na(+). Has a high affinity for sodium, but can also transport lithium. Activity is weakly pH-dependent. Essential for regulation of intracellular pH under alkaline conditions
