Detail of a subunit of the capsid, or outer cover, of bacteriophage P22, a virus that infects the Salmonella bacteria. Cryo-electron microscopy (cryo-EM) was used to capture details of the capsid proteins, each shown here in a separate color. Thousands of cryo-EM scans capture the structure and shape of all the individual proteins in the capsid and their position relative to other proteins. A computer model combines these scans into the image shown here. Related to image 5874.
