Bacteriophage T4 is a large, tailed, double-stranded DNA virus that uses Escherichia coli as a host. These images were made from a density map (22.5 angstrom resolution) obtained by electron cryo-microscopy. They show the virus head and portal to which the tail connects. More details can be found in A. Fokine, et al., PNAS (2004) 101(16):6003-8.
Images made by Steven McQuinn. A PDF file containing the all of the images is available. The data set is EMD-1075 from the Macromolecular Structure Database.
