SUBSEQUENTLY, THE PROTON- PROTON DISTANCES IN THE CALCULATED STRUCTURES WERE DETERMINED USING THE PROGRAM BACKCALC_DB 2.0 (SOFTWARE SYMBIOSE, INC., BAYREUTH, GERMANY) AND COMPARED WITH THE COMBINATIONS OF DISTANCES POSSIBLE FOR EACH FREQUENCY DEGENERATED NOESY CROSS-PEAK. IF ONLY ONE OF THE POSSIBLE DISTANCE COMBINATIONS WAS FULFILLED IN MORE THAN 50% OF THE CALCULATED STRUCTURES, THE DISTANCE INFORMATION WAS USED IN FURTHER STRUCTURE CALCULATIONS. THIS PROCEDURE WAS REPEATED SEVERAL TIMES, LEADING TO A TOTAL OF 424 INTRARESIDUAL AND 337 INTERRESIDUAL NOE CONNECTIVITIES. STRUCTURES CALCULATIONS WERE PERFORMED USING A MODIFIED AB INITIO SIMULATED ANNEALING PROTOCOL (NILGES, UNPUBLISHED) WITH X-PLOR V3.840. THE CALCULATION STRATEGY INCLUDES FLOATING ASSIGNMENT OF PROCHIRAL GROUPS AND A REDUCED PRESENTATION FOR NON-BONDED INTERACTIONS FOR PART OF THE CALCULATION TO INCREASE EFFICIENCY. A MORE DETAILED DESCRIPTION OF THE PROTOCOL IS GIVEN IN KHARRAT ET AL. (EMBO J. 14 (1995) 3572-84). STRUCTURE PARAMETERS WERE EXTRACTED FROM THE STANDARD FILES PARALLHDG.PRO AND TOPALLHDG.PRO OF X-PLOR V3.840. IN EACH ROUND OF THE STRUCTURE CALCULATION 100 STRUCTURES WERE CALCULATED. OF THE 100 STRUCTURES RESULTING FROM THE FINAL ROUND OF STRUCTURE CALCULATION, THOSE 30 STRUCTURES THAT SHOWED THE LOWEST TOTAL ENERGY VALUES WERE SELECTED FOR FURTHER CHARACTERIZATION.

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.
