| Ca(2+)-Transporting ATPase ATPase, Calcium | Adenosinetriphosphatase, Calcium | Calcium ATPase | Calcium Adenosinetriphosphatase | Calcium Pump | Adenosine Triphosphatase, Calcium | Ca2+ ATPase | Calcium-ATPase | ATPase, Ca2+ | Calcium Adenosine Triphosphatase An enzyme found in the sarcoplasmic reticulum vesicle membrane. During the relaxation of skeletal muscles and muscle rich in mitochondria, this enzyme catalyzes the active transport of calcium into the sarcoplasmic reticulum vesicles from the sarcoplasm. It requires micromolar concentrations of Ca(2+) and utilizes MgATP as a substrate. (Prog Biophys Mol Biol 1988;52(1):1). EC 3.6.1.38. |
