U VALUES WITH TLS ADDED. thiamine pyrophosphate restraints were obtained from the prodrg server, using coordinates from pdb entry 2PGN. parrot was used for density modification. Arp/warp and buccaneer were used for automated tracing. Coot was used for interactive model rebuilding and Molprobity was used for geometry validation. CAVEAT: Density for the pyrophosphate moieties of the thiamine pyrophosphate models is poorer than for the protein/ligand model as a whole. Geometry of the moiety is distorted. Anomalous difference fourier density is observed at the pyrophosphate sites. Assignment of the cation near the TPP binding site as calcium is tentative, as coordination geometry deviates from expected ideal configuration. The cation positions are supported by anomalous difference fourier density.

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.
