• PubMed Abstract: 
  

The dsDNA bacteriophage PRD1 has a membrane inside its icosahedral capsid. While its large size (66 MDa) hinders the study of the complete virion at atomic resolution, a 1.65-A crystallographic structure of its major coat protein, P3, is available. Cryo-electron microscopy (cryo-EM) and three-dimensional reconstruction have shown the capsid at 20-28 A resolution. Striking architectural similarities between PRD1 and the mammalian adenovirus indicate a common ancestor.
