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
