Abstract: Nipah virus, a member of the family, is a highly pathogenic nonsegmented, negative-sense RNA virus (nsNSV) which causes severe neurological and respiratory illnesses in humans. There are no ...Nipah virus, a member of the family, is a highly pathogenic nonsegmented, negative-sense RNA virus (nsNSV) which causes severe neurological and respiratory illnesses in humans. There are no available drugs or vaccines to combat this virus. A complex of large polymerase protein (L) and phosphoprotein (P) of Nipah virus supports replication and transcription and affords a target for antiviral drug development. Structural information required for drug development is lacking. Here we report the 2.9-angstrom cryo-electron microscopy structure of the Nipah virus polymerase-phosphoprotein complex. The structure identifies conserved amino acids likely important for recognition of template RNA by nsNSVs and reveals the locations of mutation-prone sites among Nipah virus strains, which may facilitate the development of therapeutic agents against Nipah virus by targeting regions unaffected by these mutation sites.

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.

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.
