A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 7.2.2.19

Accepted Name
H(+)/K(+)-exchanging ATPase.
Alternative Name(s)
Gastric H(+)/K(+) ATPase.
H(+)/K(+)-ATPase.
Potassium-transporting ATPase.
Proton pump.
Reaction catalysed
ATP + H(2)O + H(+)[side 1] + K(+)[side 2] <=> ADP + phosphate + H(+)[side 2] + K(+)[side 1]
Cofactor(s)
Mg(2+).
Comment(s)
  • A P-type ATPase that undergoes covalent phosphorylation during the transport cycle.
  • A gastric mucosal enzyme that catalyzes the efflux of one H(+) and the influx of one K(+) per ATP hydrolyzed.
  • Formerly EC 3.6.1.36 and EC 3.6.3.10.
