Bacteriophage P22,computer model. Cutaway view of P22 created with molecular modelling software and data from cryo-electron microscopy. Bacteriophages are viruses that infect bacteria. P22 infects Salmonella enterica. The image shows a cutaway view of the virus 'head'. The outer layer (blue),known as the capsid,is made of protein. The interior contains tightly coiled DNA (green) and a group of proteins (red,pink) that form a portal. The portal acts as a molecular motor that power the packaging of DNA within the virus and during the injection of DNA into a host cell. At centre bottom are proteins (orange) that form the 'tail'.
