7.2.2.6 |
| Accepted name: |
P-type K+ transporter |
| Reaction: |
ATP + H2O + K+[side 1] = ADP + phosphate + K+[side 2] |
| Other name(s): |
K+-translocating Kdp-ATPase; multi-subunit K+-transport ATPase; K+-transporting ATPase; potassium-importing ATPase; K+-importing ATPase |
| Systematic name: |
ATP phosphohydrolase (P-type, K+-importing) |
| Comments: |
A P-type ATPase that undergoes covalent phosphorylation during the transport cycle. A bacterial enzyme that is involved in K+ import. The probable stoichiometry is one ion per ATP hydrolysed. |
