Abstract:

Introduction. In previous studies it could be shown that autolytic wall enzymes of bacteria can be activated by some cationic proteins (1). Recently we determination of firming our data lytic enzyme but obtained results from chemical and end group determination of the cleavage products from peptidoglycan confirming our data that even lysozyme acted not only as a muralytic enzyme but also as a cationic protein (2). In order to elucidate the mechanisms of the activation of autolytic wall processes by cationic proteins and of the direct respectively indirect muralytic actions of lysozyme we performed investigations on heated cells.
