Virus Capsid Reveals Surprises

Improved resolution uncovers a second protein in outer protein shell

A team of researchers has pushed the resolution of single-particle electron cryomicroscopy (cryo-EM) to levels that allow them to trace the backbone of the 22-megadalton capsid, or outer protein shell, of the ε15 bacteriophage, a virus that infects the bacterium Salmonella anatum (Nature 2008, 451, 1130).
