Details: 1 uL of 24 mg/mL MCR was mixed with 1 uL of well solution (27% (w/v) PEG400, 0.18 M magnesium acetate, 0.25 M sodium chloride, and 0.10 M HEPES pH 7.5) to make a 2-uL sitting drop in a ...Details: 1 uL of 24 mg/mL MCR was mixed with 1 uL of well solution (27% (w/v) PEG400, 0.18 M magnesium acetate, 0.25 M sodium chloride, and 0.10 M HEPES pH 7.5) to make a 2-uL sitting drop in a sealed well with 30 uL well solution. Yellowish green rod MCR crystals grew in two to four hrs. The entire crystallization plate was shipped to Advanced Light Source Beamline 8.2.2 for Xe- pressurization and data collection. The crystals used to determine Xe-derivatized structure were transferred from the sitting drop into 2-5 uL of paraffin oil briefly and then sealed in a steel chamber pressurized with xenon at 180 psi for 10 mins. The Xe-derivatized crystals were flash-cooled in liquid nitrogen for data collection immediately.

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.
