Note that this reaction equation differs from the official Enzyme Commission reaction equations for this EC number.
Reaction Locations: inner membrane (sensu Gram-negative Bacteria)
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.
Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.
Mass balance status: Balanced.
Enzyme Commission Primary Name: K+-transporting ATPase
Enzyme Commission Synonyms: K+-translocating Kdp-ATPase, multi-subunit K+-transport ATPase
Enzyme Commission Summary:
A 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 hydrolysed.
