Virus evolution has ...For nearly 30 years, Goose/Guangdong-derived highly pathogenic avian influenza H5N1 viruses have posed significant risks to economic stability, food security, and public health. Virus evolution has resulted in various clades, including the panzootic subclade 2.3.4.4b, recognized for its pandemic potential. Here we present the potent in vitro activity of FNI9, a pan-influenza NA-inhibiting monoclonal antibody, against a range of pseudoparticles with NA spanning decades of H5N1 virus evolution. FNI9 also shows strong prophylactic protection in female mice against lethal challenges with H5N1 from clade 1 and 2.3.4.4b. Cryo-EM and molecular dynamics analysis reveal that FNI9 binds to 7 highly conserved H5N1 NA residues (R118, E119, D151, E228, E278, R293, and R368). In silico evolutionary escape profiling and machine learning predict low escapability, high fitness costs, and minimal spread likelihood for viral mutations that evade FNI9 binding. These findings support FNI9 broad protection and underscore the NA role in future influenza vaccine design.

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.
