DetailsThe depositor states that the biological assembly is hexameric, not heptameric. Orc2 was deposited as 2 different chains because the N-terminus could only be built as a discontinuous polyalanine model. However, both chains belong to the same polypeptide.

Details

Sequence detailsTHE AUTHOR STATES THAT CHAIN G IS LIKELY PART OF THE N-TERMINUS OF CHAIN B. 61 N-TERMINAL RESIDUES ...THE AUTHOR STATES THAT CHAIN G IS LIKELY PART OF THE N-TERMINUS OF CHAIN B. 61 N-TERMINAL RESIDUES ARE MISSING (DISORDERED). OWING TO LOW RESOLUTION, IT WAS NOT POSSIBLE TO ACCURATELY ASSIGN THE SIDE CHAINS AND IDENTIFY THE PEPTIDE. THE N-TERMINUS WAS MODELED AS ALA, BUT THE SEQUENCE ALIGNMENT IS UNKNOWN, AND WAS THEREFORE CHANGED TO UNK IN 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.

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.
