Strongest one with vector (0.4029 0.50000.618), second one (0.1953 0.000 0.7638), and third one at (0.2092 0.5000 0.8536), corresponding to 1X Td, 2X Td and 3X Td, respectively, with relative intensities to orgin peak of ~65%, ~30% and 8.5% (CCP4 fft used; phenix.xtriage showed even higher values like 73%, 34% and 10%, most likely due to grid sampling difference), respectively. Peak 1 and 2 are mostly targeted. Peak 1 corresponds to tNCS too, so after correction it is lowered but not eliminated. Peak 2 eventually gone. Final Rwork and Rfee went down to 19.81% and 21.99%,respectively. Without correction, the Rwork and Rfree, with best try, are paused at 31.38% and 33.83%, respectively.

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.

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.
