[Regulatory role of proteolytic enzymes].

The article reviews various aspects of the regulatory function of proteolytic enzymes: their role in the biogenesis of some physiologically active proteins and peptides, in triggering and mediation of a variety of biological processes, in intracellular interactions and in metabolic refolding during adaptation. The data on localization and functions of some intracellular proteolytic enzymes, as well as data on regulation of their activity are presented. The limited proteolysis as an especial form of biological control is considered.
