DetailsAn ~ 4 Angstrom structure of the 285 kDa major fragment of bovine fibrinogen. The alpha-carbon coordinates for both molecules per asymmetric unit are provided. The molecule is a dimer of a heterotrimer. Coordinates with chain ids ABC:DEF and NOP:QRS are the two crystallographically independent dimers. A,D,N, and Q correspond to the A-alpha chain. B,E,O, and R correspond to the B-beta chain. C,F,P, and S correspond to the gamma chain. These alpha-carbon coordinates include the end gamma and beta domains (i.e. the C-terminal globular domains of the gamma and B-beta chains, respectively) and the coiled coils (which are made of the A-alpha, B-beta, and gamma chains.). The density corresponding to the central disulfide knot region is too irregular to be traced at this resolution, and only some coordinates for part of this domain are included where density is seen (designated M and Z for the for the two molecules per a.u.).

A B- ...Details: Side chains were included in refinement. At this resolution, however, the correct side chain conformations cannot be generally determined, and only alpha Carbons are deposited here. A B-factor equal to 999 identifies a residue whose density is generally relatively disordered and thus is not included in refinement (but generally positioned using information from non- crystallographically-related copies). Note that of the asymmetric unit's four half-dimers, that designated by chain ids N, O, and P has the most residues included in the refinement, and its electron density is best ordered. The central disulphide knot region could not be traced, and only some coordinates for part of this domain are included (resname=UNK, chainid M and Z for the two molecules per a.u.). Due to anisotropy in the the diffraction, the data in the highest shells (esp. 4.0-3.5) are quite incomplete, and hence the structure is judged overall to at ~4.0 angstroms resolution.

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.

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.
