ATPase activity in rat heart sarcoplasmic reticulum was stimulated in a concentration-dependent manner by both Ca 2+ and Mg > in the complete absence of the other cation. Increasing concentrations of Mg 2+ produced an apparent inhibition of the Ca>-dependent ATP hydrolysis. CDTA (trans-l,2-diaminocy
The preincubation of the rat blood cell membranes in the presence of low Ca2+ levels causes an irreversible inhibition of the Ca2+-stimulated ATPase activity. The inactivation is dependent on the Ca2+ concentration and the apparent Ki is identical to the Ca2+ concentration needed to reach the half-m
