However, unlike EBOV, there are no approved vaccines or treatments for SUDV, and its structural interaction with the endosomal receptor NPC1 remains unclear. This study compares the glycoproteins of SUDV and EBOV (in their proteolytically primed forms) and their binding to human NPC1 (hNPC1). The findings reveal that the SUDV glycoprotein binds significantly more strongly to hNPC1 than the EBOV glycoprotein. Using cryo-EM, we determined the structure of the SUDV glycoprotein/hNPC1 complex, identifying four key residues in the SUDV glycoprotein that differ from those in the EBOV glycoprotein and influence hNPC1 binding: Ile79, Ala141, and Pro148 enhance binding, while Gln142 reduces it. Collectively, these residue differences account for SUDV's stronger binding affinity for hNPC1. This study provides critical insights into receptor recognition across all viruses in the ebolavirus genus, including their interactions with receptors in bats, their suspected reservoir hosts. These findings advance our understanding of ebolavirus cell entry, tissue tropism, and host range.

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.

Jul 12, 2017. Major update of PDB

Major update of PDB

  • wwPDB released updated PDB data conforming to the new PDBx/mmCIF dictionary.
  • This is a major update changing the version number from 4 to 5, and with Remediation, in which all the entries are updated.
  • In this update, many items about electron microscopy experimental information are reorganized (e.g. em_software).
  • Now, EM Navigator and Yorodumi are based on the updated data.
