Remark 999SEQUENCE HUMAN HEMOGLOBIN HAS TWO ALPHA CHAINS WHICH ARE CALLED CHAINS A AND C IN OTHER PDB FILES. ...SEQUENCE HUMAN HEMOGLOBIN HAS TWO ALPHA CHAINS WHICH ARE CALLED CHAINS A AND C IN OTHER PDB FILES. IN THIS ENTRY THE C-TERMINUS OF THE ALPHA-1 CHAIN AND THE N-TERMINUS OF THE ALPHA-2 CHAIN ARE GENETICALLY LINKED BY THREE GLYCINE RESIDUES TO FORM ONE COVALENTLY LINKED POLYPEPTIDE CHAIN. THESE THREE RESIDUES ARE HIGHLY DISORDERED, I.E. NOT DEFINED IN ELECTRON DENSITY. ALSO, THE INITIAL RESIDUE OF THE ALPHA-2 CHAIN, JUST AFTER THE GLYCINE LINKER, IS THE NATIVE VALINE, NOT A METHIONINE. THEREFORE, THE THREE GLYCINE LINKER IS NOT INCLUDED IN THESE COORDINATES, AND THE INITIAL RESIDUE OF THE ALPHA CHAIN(S) IS MODELED AS AN ALANINE.

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.
