Ca(2+)-Transporting ATPaseAn 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.
ReticulumThe second stomach of ruminants. It lies almost in the midline in the front of the abdomen, in contact with the liver and diaphragm and communicates freely with the RUMEN via the ruminoreticular orifice. The lining of the reticulum is raised into folds forming a honeycomb pattern over the surface. (From Concise Veterinary Dictionary, 1988)
RelaxationActivity which reduces feelings of tension.
MusclesContractile tissue that produces movement in animals.
CalciumA basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
