[Aminoacid-p-nitroanilides splitting activities in the mouse human placenta (author's transl)].

Abstract

Proteolytic activities of human placental extract are determined with the aid of a sensitive micromethod, based upon the Bratton-Marshall-reaction, and aminoacid-p-nitroanilides as substrates. The activities are differentiated by using 19 substrates, by adding 10 effectors, and by incubating the assays within the pH-range from 6.0--8.4. Besides Oxitocinase- and Aminopeptidase-like activities, a very active neutral peptidase, so far unknown in human placenta, an acid peptidase, e.g. Cathepsin C or Dipeptide-aminopeptidase II, and some other enzymes, not yet indentified by us, are demonstrated.
