A REGION ENCOMPASSING 11 RESIDUES INCLUDING THE LINKER COULD NOT BE MODELED DUE TO THE LACK OF INTERPRETABLE ELECTRON DENSITY. WE FAVOR THE INTERPRETATION THAT THE LINKED CHAIN OCCURS BETWEEN MOLECULES A-D, B-C. HOWEVER, AS IT IS NOT POSSIBLE TO MODEL THE LINKER REGION WITH CERTAINTY WE CANNOT EXPLICITLY DETERMINE WHICH MOLECULES ARE LINKED IN THE CRYSTAL. FOR THIS REASON, WE HAVE LABELLED THE RRS1 AND RPS4 TIR DOMAIN MOLECULES AS SEPARATE CHAINS IN THE COORDINATE FILE DEPOSITED. THE FUNCTIONALLY IMPORTANT HETERODIMERISATION INTERFACE BETWEEN RRS1 AND RPS4 TIR DOMAINS OCCURS BETWEEN PROTEIN CHAINS A-B AND C-D.

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.
