ABSTRACT

The distribution of proteinase activity in various glandular structures of the digestive system of the veined whelk Rapana venosa was investigated. Maximal proteolytic activity and variety of molecular forms of enzymes were registered in the salivary glands, and minimal proteolytic activity was registered in hepatopancreas and the Leiblein gland. Using specific inhibitors it was established that the proteolytic activity of the salivary glands was caused mainly by metalloproteinases.
