THE MODEL FOR THE N-TERMINAL DOMAIN (RESIDUES 100 - 260) INCLUDES TWO ZINC IONS AND 3 CALCIUM IONS. ZINC 998 IS AT THE ACTIVE SITE AND COORDINATES HIS 218, HIS 222, AND HIS 228. ZINC 997 APPEARS TO HAVE A STRUCTURAL ROLE AND COORDINATES HIS 168, HIS 183, AND HIS 196. THE THREE CALCIUM IONS IN THE CATALYTIC DOMAIN ARE NUMBERED 993, 995, AND 996. THE LINKING PEPTIDE CONSISTS OF RESIDUE 261 - 277. THE C-TERMINAL HAEMOPEXIN LIKE DOMAIN CONSISTS OF RESIDUES 278 - 470 AND CONTAINS ONE ZINC ION LABELED AS 994.

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.
