CrystalDensity Matthews: 2.1 Å3/Da / Density % sol: 41.4 %
Crystal growTemperature: 293 K / Method: vapor diffusion, hanging drop
Details: SpaO(145-213) + SpaO (232-297) + OrgB(1-30)::T4 lysozyme was concentrated to 18.5mg/mL and crystallized with 25% PEG3350, 200mM ammonium formate, 100mM sodium acetate pH=5.0. Microseeding ...Details: SpaO(145-213) + SpaO (232-297) + OrgB(1-30)::T4 lysozyme was concentrated to 18.5mg/mL and crystallized with 25% PEG3350, 200mM ammonium formate, 100mM sodium acetate pH=5.0. Microseeding was employed to enhance crystal uniformity and diffraction. Briefly, crystals to be seeded were harvested in precipitant solution and vortexed in a microfuge tube with a small stir bar for ~60 seconds. The slurry of microseeds was serially dilluted (5-10-fold steps) in precipitant solution and 5 selected microseed-precipitant mixtures were mixed with fresh protein as in a normal hanging drop experiment. Crystals were cryoprotected in 30% PEG3350, 10% glycerol, 200mM ammonium acetate, 100mM sodium acetate pH=5.0.

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.
