A MET-INHIBITION PROTOCOL WAS USED FOR SELENOMETHIONINE INCORPORATION DURING PROTEIN EXPRESSION. THE OCCUPANCY OF THE SE ATOMS IN THE MSE RESIDUES WAS REDUCED TO 0.75 FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. 3. ATOM RECORDS CONTAIN RESIDUAL B FACTORS ONLY. 4. THE B CHAIN IS SEVERELY DISORDERED. THE MODEL FOR B CHAIN WAS BUILT BASED ON THE CHAIN A WHERE DENSITY IS NOT DEFINITE. ADDITIONALLY, A291-297 HAS POOR DENSITY. 5. AN UNKNOWN LIGAND (UNL) IS MODELED FOR EACH MONOMER IN A SITE WHERE RESIDUES ARE HIGHLY CONSERVED.

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.
