PEAK VOLUMES WERE CONVERTED INTO UPPER DISTANCE LIMITS BY FOLLOWING THE METHODOLOGY OF THE PROGRAM CALIBA. 3JHNHA COUPLING CONSTANTS WERE OBTAINED FROM THE RATIO BETWEEN THE INTENSITY OF THE DIAGONAL PEAK AND THAT OF THE CROSS PEAK OF THE 3D HNHA EXPERIMENT. THE 3D STRUCTURE WAS CALCULATED WITH THE PROGRAM DYANA; THE FINAL DYANA FAMILY WAS FORMED BY THE 36 CONFORMERS WITH THE LOWEST TARGET FUNCTION. REFINEMENT WAS PERFORMED THROUGH RESTRAINED ENERGY MINIMIZATION WITH THE SANDER MODULE OF THE PROGRAM AMBER. NOESY CROSS PEAKS WERE BACK -CALCULATED ON THE FINAL STRUCTURE WITH THE PROGRAM CORMA.

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.
