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

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

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
