[Proteolytic enzymes in palatine tonsil lymphocytes]

Homogenates and subcellular lymphycyte fractions of human tonsilla palatina contained proteolytic enzymes operating in slightly acidic (pH 3.6) and slightly alkaline (pH 7.5) media. The enzymes hydrolyzed proteins (hemoglobin, protamine sulphate, kininogen) and syntheitc substrates (N-benz-d,1-arg-p-nitroanilide, N-benz-1-arg ethyl ester, hippuryl-1-lys and bradikinin). Data on localization of the proteolytic enzymes in subcellular lymphocyte fractions of human tonsilla were obtained.
