Abstract: Nonsense mutations are associated with numerous and diverse pathologies, yet effective treatment strategies remain elusive. A promising approach to combat these conditions involves the use of ...Nonsense mutations are associated with numerous and diverse pathologies, yet effective treatment strategies remain elusive. A promising approach to combat these conditions involves the use of aminoglycosides, particularly in combination with stop-codon read-through enhancers, for developing drugs that can rescue the production of full-length proteins. Using X-ray crystallography and single-particle cryo-EM, we obtained structures of the eukaryotic ribosome in complexes with several aminoglycosides (geneticin G418, paromomycin, and hygromycin B) and the antimalarial drug mefloquine (MFQ), which has also been identified as a read-through enhancer. Our study reveals a binding site of MFQ, which holds significant promise for the development of therapies targeting premature termination codon-related genetic and oncological diseases. The results underscore the crucial role of the bridge B7b/c in mediating the effects of MFQ on subunit rotation dynamics. Through a comprehensive analysis of the interactions between the drugs and the eukaryotic ribosome, we propose a unifying hypothesis for read-through enhancement by small molecules, highlighting the role of decoding center rearrangements and intersubunit rotation dynamics.

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.
