[Properties of glucocorticoid-sensitive alkaline proteinases of rat target organs]

The preliminary characterization of glucocorticoid-sensitive alkaline proteinases of rats thymus and liver was carried out. The role of active serine and cysteine residues in proteolysis was estimated. The influence of Ca++, Mg++, Fe++, Fe , Cu++, EDTA and EGTA on enzymes activity was studied. It is shown that the alkaline proteinases of thymus and liver have similar properties, but are not completely identical.
