[Proteolysis in digestive system regulation].

Signal enzymes with direct and indirect hormone releasing action are formed by means of proteolysis from exogenic and endogenic proteins. The proteolysis is the basis of hormone processing. The limited proteolysis forms hormones from pro-hormones, ligand proteolysis excludes or reduces their stimulated or inhibited effects. The existence of polipotent proteinaso-activated receptors with regulative and modulated role in norm and pathology was proved.
