Bacteriophage-encoded virion-associated enzymes to overcome the carbohydrate barriers during the infection process [PDF]

open access: yes, 2017
Bacteriophages are bacterial viruses that infect the host after successful receptor recognition and adsorption to the cell surface. The irreversible adherence followed by genome material ejection into host cell cytoplasm must be preceded by the passage ...
