N-TERMINAL ...HUMAN ALPHA THROMBIN COMPRISES AMINO ACID RESIDUES 1H TO 247 (CHYMOTRYPSIN NUMBERING). N-TERMINAL SEQUENCES OF THE CENTRAL "E" REGION OF HUMAN FIBRIN START FROM RESIDUE 17 FOR ALPHA CHAINS (CHAINS G, J), 15 FOR BETA CHAINS (CHAINS H, K), AND 1 FOR GAMMA CHAINS (CHAINS I, L). C-TERMINAL SEQUENCES OF ALPHA, BETA, AND GAMMA CHAINS WERE NOT DETERMINED. DUE TO THE LACK OF ELECTRON DENSITY THROMBIN RESIDUES 1H THROUGH 1E AND RESIDUE 247 COULD NOT BE BUILD, AS WELL AS RESIDUES 17 THROUGH 28 OF FIBRIN ALPHA CHAINS, 15 THROUGH 53 OF FIBRIN BETA CHAINS, AND 1 THROUGH 5 OF FIBRIN GAMMA CHAINS.

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.
