[Alanine aminopeptidases from small intestinal mucosa of dogs, rabbits and trout. I. Characterization of the "protease forms"].
Alanine aminopeptidases from the mucous membranes of the small intestines of dog, rabbit and trout were concentrated 200 fold in the case of dog and rabbit, and 15 fold in the case of trout. The enzymes were analyzed with respect to substrate specificity, effector behaviour, optimum pH value, Michaelis constants and molecular weight. The values obtained for these enzymes are not consistent in all points with those found for alanine aminopeptidases isolated from the mucous membrane of human jejunum and ileum.
