Method to determine structure: MOLECULAR REPLACEMENT Starting model: HIV-1 PROTEASE Resolution: 1.8→20 Å / σ(F): 3 Details: THE TWO ORIENTATIONS OF THE INHIBITOR CREATED IN THE ACTIVE ENZYME OVERLAP WITH COMPLETE SUPERPOSITION AT THE PERIPHERY AND SOME DEVIATION IN THE CENTER. RESIDUES 56 - 57 HAVE BEEN MODELED ...Details: THE TWO ORIENTATIONS OF THE INHIBITOR CREATED IN THE ACTIVE ENZYME OVERLAP WITH COMPLETE SUPERPOSITION AT THE PERIPHERY AND SOME DEVIATION IN THE CENTER. RESIDUES 56 - 57 HAVE BEEN MODELED WITH TWO ORIENTATIONS OF THEIR MAIN CHAINS, SINCE THEY FORM ALTERNATE HYDROGEN BONDS, DUE TO THE SAME DISORDER PHENOMENON.

Feb 9, 2022. New format data for meta-information of EMDB entries
New format data for meta-information of EMDB entries
Version 3 of the EMDB header file is now the official format.
The previous official version 1.9 will be removed from the archive.
In the structure databanks used in Yorodumi, some data are registered as the other names, "COVID-19 virus" and "2019-nCoV". Here are the details of the virus and the list of structure data.
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 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.
