Abstract: Human noroviruses (HuNoVs) cause sporadic and epidemic viral gastroenteritis worldwide. The GII.4 variants are responsible for most HuNoV infections, and GII.4 virus-like particles (VLPs) are being ...Human noroviruses (HuNoVs) cause sporadic and epidemic viral gastroenteritis worldwide. The GII.4 variants are responsible for most HuNoV infections, and GII.4 virus-like particles (VLPs) are being used in vaccine development. The atomic structure of the GII.4 capsid in the native T = 3 state has not been determined. Here we present the GII.4 VLP structure with T = 3 symmetry determined using X-ray crystallography and cryo-EM at 3.0 Å and 3.8 Å resolution, respectively, which reveals unanticipated novel features. A novel aspect in the crystal structure determined without imposing icosahedral symmetry is the remarkable adaptability of the capsid protein VP1 driven by the flexible hinge between the shell and the protruding domains. In both crystal and cryo-EM structures, VP1 adopts a stable conformation with the protruding domain resting on the shell domain, in contrast to the 'rising' conformation observed in recent cryo-EM structures of other GII.4 VLPs. Our studies further revealed that the resting state of VP1 dimer is stabilized by a divalent ion, and chelation using EDTA increases capsid diameter, exposing new hydrophobic and antigenic sites and suggesting a transition to the rising conformation. These novel insights into GII.4 capsid structure, stability, and antigen presentation may be useful for ongoing vaccine development.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

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

Thousand views of thousand structures

  • 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.
