Protein

ATPase 8, plasma membrane-type

Gene

AHA8

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

The plasma membrane H+ ATPase of plants and fungi generates a proton gradient that drives the active transport of nutrients by H+-symport. The resulting external acidification and/or internal alkinization may mediate growth responses (By similarity).By similarity

Catalytic activityi

ATP + H2O + H+(In) = ADP + phosphate + H+(Out).
