THE OCCUPANCY OF THE SE ATOMS IN THE M RESIDUES WAS REDUCED TO 0.7 TO ACCOUNT FOR THE REDUCED SCATTERING DUE TO PARTIAL S-MET INCORPORATION. 3. THE ELECTRON DENISTY FOR RESIDUES 246-247 WAS DIFFICULT TO INTERPRET AND MAY BE POORLY MODELLED. 4. UNL (UNKNOWN LIGAND) WAS MODELLED INTO EXTRA DENSITY NEAR RESIDUES 247-249. THIS REGION MAY DENOTE THE PROTEIN ACTIVE SITE. 5. ADDITIONAL DENSITY NEAR UNL WAS INTERPRETED TO BE WATER. 6. ATOM RECORD CONTAINS RESIDUAL B FACTORS ONLY. THE MEAN B VALUE INCLUDING THE INDIVIDUAL AND TLS COMPONENTS IS 20.7 A**2.

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.
