Title: Structures of the measles virus polymerase complex with non-nucleoside inhibitors and mechanism of inhibition.

Abstract: The measles virus (MeV), a highly contagious non-segmented negative-sense RNA virus in the Paramyxoviridae family, causes millions of infections annually, with no approved antivirals available. The ...The measles virus (MeV), a highly contagious non-segmented negative-sense RNA virus in the Paramyxoviridae family, causes millions of infections annually, with no approved antivirals available. The viral polymerase complex, comprising the large (L) protein and the tetrameric phosphoprotein (P), is a key antiviral target. We determined the cryo-electron microscopy structures of the MeV polymerase complex alone and bound to two non-nucleoside inhibitors, ERDRP-0519 and AS-136A. Inhibitor binding induces a conformational change in the catalytic loop, allosterically locking the polymerase in an inactive "GDN-out" state. These findings led to the proposal that ERDRP-0519 would also be effective against Nipah virus (NiV), a highly pathogenic virus with no available antivirals. This proposal was confirmed by structure determination of the NiV polymerase complex and by inhibition of transcription.

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.
