[Amino acid-p-nitroanilide-splitting activities in human serum (author's transl)].
Proteolytic, arylamidase-like activities of human serum are determined by using a sensitive micromethod, based upon the Bratton-Marshall-reaction, and amino acid-p-nitroanilides as substrates. Besides the alanine-aminopeptidase and the oxytocinase, the dipeptide-aminopeptidase II, a neutral peptidase, and 6 other peptidases, not yet identified by us, are differentiated with the aid of 19 substrates, by adding 8 effectors, and by incubating the enzyme tests within the pH range 6.0 to 8.4.
