Enzyme Information

3.6.3.12
Potassium-transporting ATPase.
based on mapping to UniProt P03960
ATP + H(2)O + K(+)(Out) = ADP + phosphate + K(+)(In).
-!- P-type ATPase that undergoes covalent phosphorylation during the transport cycle. -!- A bacterial enzyme of di(heterotetrameric) structure that is involved in K(+) import. -!- The probable stoichiometry is one ion per ATP hydrolyzed.
