A Study of the Complex of Proteolytic Enzymes and Their Protein Inhibitors in the Embryogenesis of the Silkworm

We studied changes in the activities of serin, thiol, and aspartyl proteinases and their protein inhibitors during embryogenesis of the silkworm. The dynamics of the activities of the protein inhibitors and specific proteinases were interrelated, thus providing for the coordination and fine regulation of the functioning of the proteolytic complex of enzymes during embryogenesis. Possible functions of peptidohydrolases and their protein inhibitors in the silkworm are discussed.
