However, the structure of ribosomes from only a limited number of organisms has been resolved to date; it especially concerns plant ribosomes and ribosomal subunits. Here, we report a high-resolution cryo-electron microscopy reconstruction of the small subunit of the (common wheat) cytoplasmic ribosome. A detailed atomic model was built that includes the majority of the rRNA and some of the protein modifications. The analysis of the obtained data revealed structural peculiarities of the 40S subunit in the monocot plant ribosome. We applied the 3D Flexible Refinement approach to analyze the internal mobility of the 40S subunit and succeeded in decomposing it into four major motions, describing rotations of the head domain and a shift in the massive rRNA expansion segment. It was shown that these motions are almost uncorrelated and that the 40S subunit is flexible enough to spontaneously adopt any conformation it takes as a part of a translating ribosome or ribosomal complex. Here, we introduce the first high-resolution structure of an isolated plant 40S subunit and the first quantitative analysis of the flexibility of small ribosomal subunits, hoping that it will help in studying various aspects of ribosome functioning.

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.
