(C) A PEG molecule lies on a symmetry axis (special position) and has been modelled with occupancy=0.5. (D) Some cardiolipins molecules have been modelled with partial occupancy, as described in the accompanying paper. (E) Met250-Ser252 and Lys257 lie in very weak electron density. Their position is supported by good electron density obtained from an earlier crystal. (F) There are unmodelled bits of electron density near the N-terminus of the carrier, which are likely to be lipid headgroups/tails. (G) Additional electron density at the C-terminus of the carrier indicates where the C-terminal tail is likely to run, but it is not possible to model this accurately. (H) The structure factor file contains a second data block containing the structure factors from a crystal of BKA-inhibited TtAac grown without the nanobody. This P212121 crystal diffracted to lower resolution and with significant anisotropy, but was used to confirm the domain positions observed in the P3221 crystal of the TtAac-Nb complex.

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.
