Remark 300BIOMOLECULE: 1 THIS ENTRY CONTAINS THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT WHICH CONSISTS OF 2 CHAIN(S) ...BIOMOLECULE: 1 THIS ENTRY CONTAINS THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT WHICH CONSISTS OF 2 CHAIN(S). FACTOR XA FORMS A COMPLEX WITH FACTOR VA IN THE PRESENCE OF CALCIUM AND A PHOSPHOLIPID MEMBRANE TO PRODUCE THE PROTHROMBINASE COMPLEX. THIS ENTRY CONTAINS THE EPIDERMAL GROWTH FACTOR LIKE DOMAIN 2(L) AND THE CATALYTIC DOMAIN (A) OF FACTOR XA IN THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT. THE COORDINATES DO NOT CONTAIN THE GLA DOMAIN OR THE EPIDERMAL GROWTH FACTOR LIKE DOMAIN 1 OF FACTOR XA. ALTHOUGH THE ASYMMETRIC UNIT CONTAINS A FUNCTIONAL PROTEASE, IT DOES HAVE THE SAME SPECIFICITY AS THE PROTHROMBINASE COMPLEX. SEE REMARK 350 FOR INFORMATION ON GENERATING THE BIOLOGICAL MOLECULE(S).

THE PROTEIN ...Details: A THREE-FOLD EXCESS OF A PROPRIETARY FACTOR XA INHIBITOR WITH PICOMOLAR AFFINITY WAS ADDED TO THE DES-GLA-FACTOR XA. THIS INHIBITOR IS BASED ON THE SAME TEMPLATE AS XLD IN 1MQ6. THE PROTEIN WAS THEN CONCENTRATED TO 12-17 MG/ML. CRYSTALS WERE GROWN USING 2 UL OF COMPLEX WITH 2 UL OF RESERVOIR CONTAINING 15-21% PEG1500 AND 10 MM CACL2. 30-40 UL SITTING DROPS CONTAINING SATURATED INHIBITOR (5 MM) IN 21% PEG1500, 5 MM CACL2, 20 MM NACL, 25 MM TRIS PH 7.5 (CRYSTAL SOAKING SOLUTION) WERE EQUILIBRATED OVER A 1 ML RESERVOIR CONTAINING THE CRYSTAL SOAKING SOLUTION FOR 1 TO 2 DAYS. A SINGLE FACTOR XA CRYSTAL WAS TRANSFERRED USING A MOUNTED CRYOLOOP INTO ONE OF THESE SITTING DROPS AND ALLOWED TO SOAK FOR THREE OR MORE DAYS. AFTER THE INITIAL SOAK, EACH CRYSTAL WAS THEN TRANSFERRED TO AN UNUSED DROP AND ALLOWED TO SOAK FOR SECOND PERIOD OF THREE OR MORE DAYS. pH 7.50, VAPOR DIFFUSION, HANGING DROP, temperature 293K

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.

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.
