Protein
Calcium-transporting ATPase 4, plasma membrane-type
Gene
ACA4, At2g41560, T32G6.8
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status

Functioni

This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol into small vacuoles.

Catalytic activityi

ATP + H2O + Ca2+(Side 1) = ADP + phosphate + Ca2+(Side 2).

Enzyme regulationi

Activated by calmodulin.
