HALF THE MOLECULE WAS INCLUDED IN THE REFINEMENT WHILE THE OTHER HALF WAS GENERATED BY THE SYMMETRY OPERATION. WATER MOLECULES W302, W28, W350 ALSO LOCATED ON THE SAME SYMMETRY AXIS WERE KEPT FIXED IN POSITION DURING THE REFINEMENT. THERE WAS NO OBSERVABLE DENSITY FOR THE RESIDUES 1-9, AS WELL AS FOR 126- 127 OF BOTH THE CHAINS. THIS COORDINATE SET COMPRISES TWO CHAINS REPRESENTING TWO CHEMICALLY EQUIVALENT, BUT CRYSTALLOGRAPHICALLY DISTINCT, ENTITIES. THE OTHER HALF OF THE COMPLETE TETRAMER CAN BE GENERATED FROM THIS DIMER BY THE APPLICATION OF THE CRYSTALLOGRAPHIC TWO-FOLD SYMMETRY ALONG Z THROUGH THE ORIGIN OF THE COORDINATE SYSTEM.

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.
