Rabbit muscle cathepsin H classified as an aminoendopeptidase was purified and its properties were investigated to clarify its contribution to the proteolysis of postmortem muscle. The purification was performed by ammonium sulfate fractionation and successive chromatographies on Sephadex G-75, phosphocelluose

An intracellular alpha-aminoacyl-peptide hydrolase (EC 3.4.11.-) from Naegleria fowleri nN68 (ATCC 30894) has been characterized. The enzyme preparation hydrolyzed phenylalanyl-, tyrosyl-, leucyl-, arginyl-, alanyl-, tryptophanyl-, histidyl-, methionyl-, and lysyl-naphthylamide but not benzoylleucyl-, leucylglycyl-, glycylprolylleucyl-, glycyl-, threonyl-, aspartyl-, or glutamyl-naphthylamide.

The mode of action towards oligopeptides and proteins of hydrolase H purified from rabbit skeletal muscle was studied. The presence of protamine or alpha-N-benzoylarginine p-nitroanilide (an endopeptidase substrate) changed both the Km and V values of the enzyme towards Leu-beta-naphthylamide

The regulation of amino-oligopeptidase (AOP), an intestinal brush border hydrolase essential for the surface digestion of peptide nutrients, was examined in rats in vivo. Short-term (30-minute) intraintestinal perfusion of a tetrapeptide substrate, Gly-Leu-Gly-Gly, or a synthetic substrate, leucyl-beta-naphthylamide, induced a
Proteolytic activity in the placenta, decidua and postimplantation embryos of the rat.
