Bacteriophage portal proteins. Molecular model showing the structure of a complex of bacteriophage P22 portal protein (centre left) bound to middle tail factor GP4 (far left) and a long thin barrel section (centre right). Bacteriophages are viruses that infect bacteria,with their genetic material injected into the host cell through protein complexes such as this. For a close-up of the circular structure at lower left,see C014/7686). This structure inserts deeply into the virion and similar to a rifle barrel increases the accuracy of ejection of genetic material into the host cell. The P22 bacteriophage infects enterobacteria | |
