Crystal growMethod: vapor diffusion, sitting drop / pH: 7.5
Details: HSCKALPHA1 AT 20 MG/ML WAS PREINCUBATED AT ROOM TEMPERATURE WITH 12 MM OF COMPOUND BR25 IN BUFFER 25 MM TRIS/HCL, 150 MM NACL PH 7.5 (DMSO IS AT 5% FINAL CONCENTRATION IN THE MIX). THE ...Details: HSCKALPHA1 AT 20 MG/ML WAS PREINCUBATED AT ROOM TEMPERATURE WITH 12 MM OF COMPOUND BR25 IN BUFFER 25 MM TRIS/HCL, 150 MM NACL PH 7.5 (DMSO IS AT 5% FINAL CONCENTRATION IN THE MIX). THE SITTING-DROP VAPOUR DIFFUSION METHOD WAS USED TO PRODUCE CRYSTALS BY MIXING 0.5 MICROL OF THE PROTEIN SOLUTION AND AN EQUAL VOLUME OF MOTHER LIQUOR (20% PEG 5000 MME AND 0.2 M KSCN). TETRAGONAL CRYSTALS (SPACE GROUP P43212) GREW WITHIN 2-4 DAYS AND THEN WERE SOAKED FOR ONE DAY WITH 20 MM COMPOUND BR25 SOLVED IN 100% DMSO. THE CRYSTALS USED IN THIS STUDY WERE CRYOPROTECTED IN MOTHER LIQUOR SOLUTIONS CONTAINING 20 % ETHYLENGLYCOL AND FROZEN IN A NITROGEN GAS STREAM COOLED TO 100 K.

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.
