Here, we report the ...The diamide insecticide class is one of the top-selling insecticides globally. They are used to control a wide range of pests by targeting their ryanodine receptors (RyRs). Here, we report the highest-resolution cryo-electron microscopy (cryo-EM) structure of RyR1 in the open state, in complex with the anthranilic diamide chlorantraniliprole (CHL). The 3.2-Å local resolution map facilitates unambiguous assignment of the CHL binding site. The molecule induces a conformational change by affecting the S4-S5 linker, triggering channel opening. The binding site is further corroborated by mutagenesis data, which reveal how diamide insecticides are selective to the Lepidoptera group of insects over honeybee or mammalian RyRs. Our data reveal that several pests have developed resistance via two mechanisms, steric hindrance and loss of contact. Our results provide a foundation for the development of highly selective pesticides aimed at overcoming resistance and therapeutic molecules to treat human myopathies.

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.

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.

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.
