Magn. Res., 138, 334-342, 1999). The fragments were reassembled and then positioned spatially by translation using a limited set of NOEs to produce a backbone fold of the nodF protein. THERE ARE N-CA-C ANGLE ERRORS (AS COMPARED TO THE STANDARD DICTIONARY) AT RESIDUES 13 AND 80. RESIDUE 80 LIES SOMEWHAT OUTSIDE ALLOWED RAMACHANDRAN SPACE. THESE SITES ARE POSITIONS WHERE ORIENTED HELICAL FRAGMENTS WERE REASSEMBLED INTO COMPLETE HELICES DURING DETERMINATION OF OF THE BACKBONE FOLD AND ANY SMALLER LOCAL DISTORTIONS FROM IDEALITY ARE EXPECTED TO CONCENTRATE HERE. THE STRUCTURE PRESENTED HERE CONTAINS ONLY COORDINATES FOR BACKBONE ATOMS INVOLVED IN SECONDARY STRUCTURE. THE STRUCTURE IS THE AVERAGE OF AN ENSEMBLE WITH A HEAVY ATOM RMSD OF 2.4 ANGSTROMS. CB POSITIONS COME FROM POLYALANINE HELICES USED TO MODEL THE BACKBONE.

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.
