Sequence changes in ZIKV since its first isolation are apparent when pre-epidemic strains are compared with those causing the current epidemic. However, the residues that are responsible for ZIKV pathogenicity are largely unknown. Here we report the cryo-electron microscopy (cryo-EM) structure of the immature ZIKV at 9-Å resolution. The cryo-EM map was fitted with the crystal structures of the precursor membrane and envelope glycoproteins and was shown to be similar to the structures of other known immature flaviviruses. However, the immature ZIKV contains a partially ordered capsid protein shell that is less prominent in other immature flaviviruses. Furthermore, six amino acids near the interface between pr domains at the top of the spikes were found to be different between the pre-epidemic and epidemic ZIKV, possibly influencing the composition and structure of the resulting viruses.

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.
