Journal: Nat Commun / Year: 2019 Title: Atomic structure of the Epstein-Barr virus portal. Authors: Cristina Machón / Montserrat Fàbrega-Ferrer / Daming Zhou / Ana Cuervo / José L Carrascosa / David I Stuart / Miquel Coll / Abstract: Herpesviridae is a vast family of enveloped DNA viruses that includes eight distinct human pathogens, responsible for diseases that range from almost asymptomatic to severe and life-threatening. ...Herpesviridae is a vast family of enveloped DNA viruses that includes eight distinct human pathogens, responsible for diseases that range from almost asymptomatic to severe and life-threatening. 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.

In the structure databanks used in Yorodumi, some data are registered as the other names, "COVID-19 virus" and "2019-nCoV". Here are the details of the virus and the list of structure data.

EMDB accession codes are about to change! (news from PDBe EMDB page)
The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
The EM Navigator/Yorodumi systems omit the EMD- prefix.

Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
