Protein
Plasma membrane ATPase
Organism
Dunaliella acidophila
Function
The plasma membrane ATPase of plants and fungi is a hydrogen ion pump. The proton gradient it generates drives the active transport of nutrients by H(+)-symport. The resulting external acidification and/or internal alkinization may mediate growth responses.
Similarity
Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIIA subfamily.
