BOTH CONSTRUCTS WERE EXPRESSED WITH AN N-TERMINAL PURIFICATION TAG MGSDKIHHHHHHENLYFQG. THE TAGS WERE REMOVED WITH TEV PROTEASE LEAVING ONLY A GLYCINE (0) FOLLOWED BY RESIDUES 85-112 OF THE TARGET SEQUENCE OF UNIPROTKB ID P26369 AND RESIDUES 418-530 OF THE TARGET SEQUENCE OF UNIPROTKB ID Q8VH51.THE SEQUENCE NUMBERING OF UNIPROTKB P26369 IS BASED ON THE ISOFORM THAT MATCHES THE CANONICAL HUMAN ISOFORM UNIPROT ID P26368, AND THE SEQUENCE NUMBERING OF UNIPROT Q8VH51 IS BASED ON ISOFORM 1 OF THIS TARGET. IN THE Q8VH51 CONSTRUCT ASN 468 HAS BEEN MUTATED TO A TYR.

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.
