cpa did not influence the crystallization of ca2+-atpase by vanadate or the reaction of fluorescein-5'-isothiocyanate with the ca2+-atpase , but it completely blocked at concentrations as low as 1-2 mol of cpa/mol of atpase the fluorescence changes induced by ca2+ and [ ethylenebis ( oxyethylenenitrilo ) ] tetraacetic acid ( egta ) in fitc-labeled sarcoplasmic reticulum and inhibited the cleavage of ca2+-atpase by trypsin at the t2 cleavage site in the presence of egta .
