CC -!- FUNCTION: This magnesium-dependent enzyme catalyzes the hydrolysis of
CC ATP coupled with the translocation of calcium from the cytosol into
CC small vacuoles.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + Ca(2+)(in) + H2O = ADP + Ca(2+)(out) + H(+) + phosphate;
CC Xref=Rhea:RHEA:18105, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:29108, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:456216; EC=7.2.2.10;
CC -!- ACTIVITY REGULATION: Activated by calmodulin.
CC -!- SUBCELLULAR LOCATION: Vacuole membrane {ECO:0000269|PubMed:11115896,
CC ECO:0000269|PubMed:17151019}; Multi-pass membrane protein
CC {ECO:0000255}. Note=Tonoplast. Small vacuoles.
CC {ECO:0000269|PubMed:11115896}.
CC -!- DOMAIN: The N-terminus contains an autoinhibitory calmodulin-binding
CC domain, which binds calmodulin in a calcium-dependent fashion.
CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC family. Type IIB subfamily. {ECO:0000305}.
