the ca2+-dependent atpase control and atp-containing samples became almost identical the ca2+-dependent atpase ( atp phosphohydrolase [ ec 3.6.1.3 ] ) of sr was protected by the presence of atp during incubation with relatively low concentrations of spin label , irrespective of the total amount of label bound , although with increasing concentration of bound label the atpase activity decreased .
