Protein

Calcium-transporting ATPase 2, endoplasmic reticulum-type

Gene

ECA2

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to an endomembrane compartment.

Catalytic activityi

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