Details: For the alignment, MBP (UNP P0AEX9, 27-392) spans residues 19-384 (w/ surface entropy reduction mutations at 100, 101, 190, 191, and 257) and is fused to a Bcl-2/Bcl-xL chimera via a linker ...Details: For the alignment, MBP (UNP P0AEX9, 27-392) spans residues 19-384 (w/ surface entropy reduction mutations at 100, 101, 190, 191, and 257) and is fused to a Bcl-2/Bcl-xL chimera via a linker sequence (AARAAA) spanning 385-390. Bcl-2 (UNP P10415, 10-207) has the unstructured loop spanning 35-91 deleted and replaced with Bcl-xL (UNP Q07817, 29-44) for residues 35-50 of the Bcl-2/Bcl-xL chimera, so Bcl-2 spans 391-415 and 432-547, while Bcl-xL spans 416-431. For the 3D model, MBP (-362-3), linker (4-9), Bcl-2 (10-34 and 92-207), and Bcl-xL (35-50). GLU91 of the final model corresponds to residue 50 (Bcl-xL) of the loop replacement (35-50).

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.
