Title: Thermophile 90S Pre-ribosome Structures Reveal the Reverse Order of Co-transcriptional 18S rRNA Subdomain Integration.

Abstract: Eukaryotic ribosome biogenesis involves RNA folding and processing that depend on assembly factors and small nucleolar RNAs (snoRNAs). The 90S (SSU-processome) is the earliest pre-ribosome ...Eukaryotic ribosome biogenesis involves RNA folding and processing that depend on assembly factors and small nucleolar RNAs (snoRNAs). The 90S (SSU-processome) is the earliest pre-ribosome structurally analyzed, which was suggested to assemble stepwise along the growing pre-rRNA from 5' > 3', but this directionality may not be accurate. Here, by analyzing the structure of a series of 90S assembly intermediates from Chaetomium thermophilum, we discover a reverse order of 18S rRNA subdomain incorporation. Large parts of the 18S rRNA 3' and central domains assemble first into the 90S before the 5' domain is integrated. This final incorporation depends on a contact between a heterotrimer Enp2-Bfr2-Lcp5 recruited to the flexible 5' domain and Kre33, which reconstitutes the Kre33-Enp-Brf2-Lcp5 module on the compacted 90S. Keeping the 5' domain temporarily segregated from the 90S scaffold could provide extra time to complete the multifaceted 5' domain folding, which depends on a distinct set of snoRNAs and processing factors.

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. (see PDBe EMDB page)
  • 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. See below links for details.
  • 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.
