[Characteristics of Ca2+ ion effect on the activity of Mg2+-dependent ATPase system in ghosts and reconstituted erythrocytes].
A good conformity if demonstrated of the kinetics of calcium ions effect on ATPase activity of human and rat erythrocyte ghosts. The increase of calcium concentration in the rat errythrocytes hemolysis medium (above 50-100 micrometer) results in a considerable aggregation of reconstructed vesicles. An activation of ouabaine-sensitive component of Mg2+-dependent ATPase under the increase of intracellular Ca2+ in reconstructed human erythrocytes is observed.
