Title: 90 pre-ribosome transformation into the primordial 40 subunit.
Authors: Jingdong Cheng / Benjamin Lau / Giuseppe La Venuta / Michael Ameismeier / Otto Berninghausen / Ed Hurt / Roland Beckmann /
Abstract: Production of small ribosomal subunits initially requires the formation of a 90 precursor followed by an enigmatic process of restructuring into the primordial pre-40 subunit. We elucidate this ...Production of small ribosomal subunits initially requires the formation of a 90 precursor followed by an enigmatic process of restructuring into the primordial pre-40 subunit. We elucidate this process by biochemical and cryo-electron microscopy analysis of intermediates along this pathway in yeast. First, the remodeling RNA helicase Dhr1 engages the 90 pre-ribosome, followed by Utp24 endonuclease-driven RNA cleavage at site A, thereby separating the 5'-external transcribed spacer (ETS) from 18 ribosomal RNA. Next, the 5'-ETS and 90 assembly factors become dislodged, but this occurs sequentially, not en bloc. Eventually, the primordial pre-40 emerges, still retaining some 90 factors including Dhr1, now ready to unwind the final small nucleolar U3-18 RNA hybrid. Our data shed light on the elusive 90 to pre-40 transition and clarify the principles of assembly and remodeling of large ribonucleoproteins.

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.
