From the highly purified but lowly active recombinant protein Destabilas-Lysozyme (Dest-Lys) by use cation-exchange column TSK CM 3-SW chromatography, it was separated non-active fraction IV, contained 90% of protein. Fractions I, II and III, represented proteins with lysozyme and isopeptidase activities. Their lysozyme activity correlates with the activity of natural Des-Lys. The ratio of the activities in fractions I – III is such, that maximal lysozyme activity is concentrated in fraction III, isopeptidase – in fraction I. It is discussed the possibility of Dest-Lys different functions regulation is depended on the formation of protein complex forms
