Ca(II)-transporting ATPase M-CSA #849 | This enzyme is a key regulator of striated muscle performance by acting as the major Ca(II)-ATPase responsible for the reuptake of cytosolic Ca(II) into the sarcoplasmic reticulum. Catalyses 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. | EC: 3.6.3.8 (PDB Primary Data) |
