[The characteristics of the properties of the membrane and cytosol peptidases of the enterocytes in different animal species].

Studies have been made on some of the properties of glycylleucyn- and leucylglycyne dipeptidases from the membrane and cytosol fractions of enterocytes of mice, rats and rabbits. Differences in cellular distribution of these enzymes in the species investigated were found. These enzymes also differ in their thermostability and the reaction to the effect of an inhibitor, 1,10-phenantrolyne. Presumably, these peptidases are presented by different enzymes which are subjected to separate genetic control.
