Abstract:The properties of cytolysin and metalloproteinase purified by different methods have been studied. The physico-chemical properties of these proteins, including their molecular weight, immunodiffusion patterns, the degree of inhibition by EDTA and diethyl pyrocarbonate, amino acid composition, cytolytic and proteolytic activity, have proved to be similar. We have come to the conclusion that cytolysin and metalloproteinase have similar composition and metalloproteinase activity determines the cytolytic and necrotic activity of the above-mentioned cytolysin.
