DetailsTHE CRYSTALLOGRAPHIC ASYMMETRIC UNIT CONTAINS TWO SUBUNITS OF THE TETRAMER. THESE SUBUNITS HAVE BEEN ASSIGNED CHAIN IDENTIFIERS *A* AND *B* AND HAVE DIFFERENT CONFORMATIONS. CHAIN A IS A *CLOSED* SUBUNIT WITH THE MG++ ION BRIDGING THE TWO PRODUCTS. CHAIN B IS AN *OPEN* SUBUNIT WITH THE MG++ BOUND TO ADP ONLY. THERE ARE TWO WATER CHAINS, ONE CORRESPONDING TO EACH SUBUNIT, AND EQUIVALENT WATER MOLECULES IN EACH CHAIN HAVE BEEN ASSIGNED THE SAME RESIDUE NUMBER. THE TETRAMER CAN BE COMPLETED FROM THE DIMER IN THIS ENTRY BY ROTATING 180 DEGREES ABOUT Z (I.E. -X, -Y, Z). THE STORED ORTHOGONAL CRYSTALLOGRAPHIC COORDINATES IN THIS ENTRY MAY BE CONVERTED TO THE MOLECULAR PQR FRAME (WITH THE MOLECULAR DIADS ALONG P,Q,R) BY THE TRANSFORMATION 0.87831 0.47808 0.00000 0.00000 0.00000 0.00000 -1.00000 -2.71300 -0.47808 0.87831 0.00000 0.00000 THE TRANSFORMATION SPECIFIED ON THE *MTRIX* RECORDS BELOW WILL YIELD APPROXIMATE COORDINATES FOR THE B CHAIN WHEN APPLIED TO THE A CHAIN. IT WILL ALSO YIELD APPROXIMATE COORDINATES FOR THE A CHAIN WHEN APPLIED TO THE B CHAIN.

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.
