ENZYME entry: EC 7.2.2.13

Accepted Name
Na(+)/K(+)-exchanging ATPase.
Alternative Name(s)
Na(+)/K(+)-ATPase.
Na,K-activated ATPase.
Sodium pump.
Sodium/potassium-transporting ATPase.
Reaction catalysed
ATP + H(2)O + Na(+)(Side 1) + K(+)(Side 2) <=> ADP + phosphate + Na(+)(Side 2) + K(+)(Side 1)
Cofactor(s)
Mg(2+).
Comment(s)
  • P-type ATPase that undergoes covalent phosphorylation during the transport cycle.
  • An enzyme from the plasma membrane of animal cells that catalyzes the efflux of three Na(+) and influx of two K(+) per ATP hydrolyzed.
  • It is involved in generating the plasma membrane electrical potential.
  • Formerly EC 3.6.1.37 and EC 3.6.3.9.
