NMR EVIDENCE ESTABLISHED THE TOPOLOGY OF THE COMPLEX TO BE A MONOMERIC ASSEMBLY IN WHICH DOMAIN F1 (PROTEIN RESIDUES 6-91) IS BOUND TO THE DNA STEM WITH THE 5' TERMINUS AND DOMAIN F2 (PROTEIN RESIDUES 109-200) TO THE DNA STEM WITH THE 3' TERMINUS; NMR FURTHER SHOWED THAT THE INDIVIDUAL BINDING MODES OF F1 AND F2 TO THEIR RESPECTIVE STEMS WAS EQUIVALENT (THOUGH IN A DIFFERENT CONTEXT) TO THOSE SEEN IN CRYSTAL STRUCTURES PDB 3ODA AND 3ODC RESPECTIVELY. TEMPLATE STRUCTURES WERE CREATED FROM 3ODA AND 3ODC (AND 1MSY AND 1RNG FOR THE DNA TETRALOOPS) AND USED TOGETHER WITH NON-CRYSTALLOGRAPHIC SYMMETRY TERMS IN XPLOR-NIH TO RETAIN THESE FEATURES IN THE CALCULATED STRUCTURES, WHILE THE RDC AND NOE DERIVED RESTRAINTS DEFINED THE OVERALL STRUCTURE. FULL DETAILS OF THE APPROACH AND THE CALCULATION PROTOCOL APPEAR IN THE PRIMARY REFERENCE AND CORRESPONDING SUPPLEMENTARY MATERIAL FOR THIS ENTRY.

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.
