Structure of the (SR)Ca2+-ATPase mutant E309Q in the Ca2-E1-MgAMPPCP form
Template:ABSTRACT PUBMED 24270570
Function
[AT2A1_RABIT] This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen. Contributes to calcium sequestration involved in muscular excitation/contraction (By similarity).
