Inhibitor, Ac-DEVD-CMK reconstituted in DMSO, was then added at a 5:1 inhibitor:peptide ratio (w/w). The protein was diluted to a concentration of 8 mg/mL by adding 10 mM Tris-HCl, pH 8.5, concentrated DTT, and concentrated NaN3 so that the final buffer consisted of 10 mM Tris-HCl, pH 8.5, 10 mM DTT, and 3 mM NaN3. Crystals were obtained at 291K by the hanging drop vapor diffusion method using 4 L drops that contained equal volumes of protein and reservoir solutions over a 0.5 mL reservoir. The reservoir solutions for optimal crystal growth consisted of 100 mM sodium citrate, pH 5.0, 3 mM NaN3, 10 mM DTT, and 10% 16% PEG 6000 (w/v). Crystals appeared within 3.5 to 6 weeks for all mutants, VAPOR DIFFUSION, HANGING DROP

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.
