This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium. Transports the calcium to the vacuole and participates in the control of the cytosolic free calcium. ATP + Ca(2+)(in) + H2O = ADP + Ca(2+)(out) + H(+) + phosphate Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family.
