Abstract
Structural Virology African swine fever virus (ASFV) is highly contagious and often lethal. With no vaccine or effective treatment, infections often require large-scale culling of pigs. Wang et al. apply cutting-edge cryo–electron microscopy techniques to determine the structure of this very large DNA virus. An 8.8-angstrom-resolution reconstruction shows the five layers of the virus, and the fourth capsid layer could be reconstructed at 4.8-angstrom resolution. The structure reveals epitopes in the major capsid protein that distinguish ASFV from other nucleocytoplasmic large DNA viruses and shows how the minor capsid proteins stabilize the capsid.
