Despite divergence in ribosome structure over the course of evolution, the catalytic site, known as the peptidyl transferase centre (PTC), is thought to be nearly universally conserved. Here we identify clades of archaea that have highly divergent ribosomal RNA sequences in the PTC. To understand how these PTC sequences fold, we determined cryo-EM structures of the 70S and 50S ribosomes to 2.4 Å and 2 Å, respectively, from the hyperthermophilic archaeon Pyrobaculum calidifontis. PTC sequence variation leads to the rearrangement of key base triples, and differences between archaeal and bacterial ribosomal proteins enable sequence variation in archaeal PTCs. Finally, we identify an archaeal ribosome hibernation factor, Dri, that differs from known bacterial and eukaryotic hibernation factors and is found in multiple archaeal phyla. Overall, this work identifies factors that regulate ribosome function in archaea and reveals a larger diversity of the most ancient sequences in the ribosome.

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.
