THE OCCUPANCY OF THE SE ATOMS IN THE MSE RESIDUES WAS REDUCED TO 0.75 FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. 2.PROTEIN ATOM RECORD CONTAINS SUM OF TLS AND RESIDUAL B FACTORS. ANISOU RECORD CONTAINS SUM OF TLS AND RESIDUAL U FACTORS. 3. NCS RESTRAINTS WERE APPLIED USING BUSTER'S LSSR RESTRAINT REPRESENTATION. 4. POTASSIUM (K) AND SULFATE (SO4) FROM THE CRYSTALLIZATION, AND ETHYLENE GLYCOL (EDO) USED AS A CRYOPROTECTANT WERE MODELED INTO THE STRUCTURE. 5. POLYETHYLENE GLYCOL FRAGMENTS (PEG,PG4,AND PGE FROM THE CRYSTALLIZATION WERE MODELED INTO THE STRUCTURE. 6.ADENOSINE-5'-DIPHOSPHATE WAS MODELED INTO THE ACTIVE SITE ON THE FOUR SUBUNITS. UN-EXPLAINED ELECTRON DENSITIES ADJACENT TO THE ADP WERE MODELED AS UNKNOWN LIGANDS (UNL).7. THE REFINEMENT WAS RESTRAINED AGAINST THE MAD PHASES. 8. TLS GROUPS WERE ASSIGNED WITH WITH THE AID OF THE TLS MOTION SERVER. 9.WATERS AND LIGANDS WERE EXCLUDED FROM TLS REFINEMENT.
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.
