Mechanism of action of the extracellular bacteriolytic enzymes of Lysobacter sp. on gram-positive bacteria: role of the cell wall anionic polymers of the target bacteria

The study of the extracellular bacteriolytic enzymes of Lysobacter sp. showed that they can efficiently hydrolyze the peptidoglycan of gram-positive bacteria provided that there is an electrostatic interaction of these enzymes with the cell wall anionic polymers, teichoic and teichuronic acids in particular. The hydrolytic action of bacteriolytic enzymes on the cell wall largely depends on the negative charge of teichoic and teichuronic acids, rather than on their chemical composition.
