Epstein-Barr virus infects B-cells and epithelial cells, causing infectious mononucleosis, as well as a number of cancers. Epstein-Barr infection cannot be cured since neither vaccine nor antiviral drug treatments are available. All herpesviruses contain a linear double-stranded DNA genome, enclosed within an icosahedral capsid. Viral portal protein plays a key role in the procapsid assembly and DNA packaging. The portal is the entrance and exit pore for the viral genome, making it an attractive pharmacological target for the development of new antivirals. Here we present the atomic structure of the portal protein of Epstein-Barr virus, solved by cryo-electron microscopy at 3.5 Å resolution. The detailed architecture of this protein suggests that it plays a functional role in DNA retention during packaging. |
