Title: Structural basis for RNA polymerase III transcription repression by Maf1.
Authors: Matthias K Vorländer / Florence Baudin / Robyn D Moir / René Wetzel / Wim J H Hagen / Ian M Willis / Christoph W Müller /
Abstract: Maf1 is a conserved inhibitor of RNA polymerase III (Pol III) that influences phenotypes ranging from metabolic efficiency to lifespan. Here, we present a 3.3-Å-resolution cryo-EM structure of yeast ...Maf1 is a conserved inhibitor of RNA polymerase III (Pol III) that influences phenotypes ranging from metabolic efficiency to lifespan. Here, we present a 3.3-Å-resolution cryo-EM structure of yeast Maf1 bound to Pol III, establishing that Maf1 sequesters Pol III elements involved in transcription initiation and binds the mobile C34 winged helix 2 domain, sealing off the active site. The Maf1 binding site overlaps with that of TFIIIB in the preinitiation complex.

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.
