Description
Summary:Experimental data indicating the polyfunctionality of lysozyme destabilase from the salivary gland secretion of the medicinal leech, a unique representative of invertebrate lysozymes, were analyzed. The destabilase combines the properties of endo-ɛ-lysyl-γ-glutamyl isopeptidase (D-dimer monomerase), lysozyme, and chitinase and simultaneously is a nonenzymatic antimicrobial agent. The polypeptide sequence of lysozyme destabilase is encoded by a family of three genes (Ds1, Ds2, and Ds3). The ability of the enzyme to hydrolyze endoisopeptide bonds formed by transglutaminases, which are detected under many pathological conditions, including thrombosis, is considered from the viewpoint of its further application in practice.
