THIS STRUCTURE IS ...Details: NEW DATA FROM PROTEUS MIRABILIS PR CATALASE COMPLEXED WITH NADPH HAVE BEEN COLLECTED AT PHOTON FACTORY, TSUKUBA, JAPAN AND THE STRUCTURE IS NOW REFINED TO 2.7 RESOLUTION. THIS STRUCTURE IS SIMILAR TO THE 3.1 A RESOLUTION STRUCTURE DESCRIBED IN REFERENCE 1 OF THIS ENTRY. REFERRING TO THIS ARTICLE, IT CAN BE NOTED THAT THE NADPH IS NOW COMPLETELY DEFINED IN THE CARDS OF ELECTRON DENSITY WHILE THE WATER MOLECULE, HOH 38, DESCRIBED AS MAYBE INVOLVED IN THE OXIDATION OF NADPH TO NADP+ IS NOT OBSERVED. WATER MOLECULES HOH 82 OF COMPOUND I STRUCTURE (2CAF) AND HOH 45 OF COMPOUND II STRUCTURE (2CAG) ARE PRESENT IN EQUIVALENT POSITION AND THE PROTEIN IS LIKELY TO BIND A WATER MOLECULE AT THIS SITE. COORDINATES FOR SIDE CHAINS OF RESIDUES 81, 204, 395, 451 AND 72, 450, 473 ARE NOT OBSERVED BEYOND CARBON CB AND CG RESPECTIVELY AND MODELED WITH AN OCCUPANCY OF 0.00 AND A TEMPERATURE FACTOR OF 99.99.

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.
