(A) Location of exopolysaccharide depolymerase degrading β-(1,6) bonds of the biofilm extracellular matrix (PIA/PNAG) of staphylococcal species in the phage particle and mode of action. (B) Location of virion-associated peptidoglycan hydrolase (VAPGH) at the phage particle and its role in the infection process. (C) Structure of Gram-positive bacteria cell wall and role of the endolysin during the bacterial lysis. (D) Activity of phage derived proteins when added exogenously and their application as anti-biofilm agents degrading polysaccharidic matrices (polysaccharide depolymerases) and lysing bacteria (VAPGHs and endolysins).
