REFINEMENTS WERE CARRIED OUT FIRST BY RIGID BODY MINIMIZATION (CLORE(2000) PROC.NATL.ACAD.SCI. 97, 9021-9025) FOLLOWED BY RESTRAINED SIMULATED ANNEALING (WANG ET AL. EMBO J. (2000) 19,5635-5649). THE CRYSTAL STRUCTURE OF THE COMPLEX BY BODE ET AL. (NATURE (1997), 389, 77-81; PDB CODE: 1UEA) HAS BEEN USED AS A STARTING POINT WITH PROTONS ATTACHED AND TAKING ONLY N-TERMINAL 126 RESIDUES OF TIMP-1. INTERFACIAL SIDE CHAINS OF THE FOLLOWING RESIDUES WERE ALLOWED TO BE FLEXIBLE: CHAIN A (MMP-3(DC)): 162-169,198-202, 205-206, 211 AND 221-223; CHAIN B (N-TIMP-1): 302-304, 329, 333-335,366-369; A TOTAL OF 49 NOE (46 INTERMOLECULAR AND 3 INTRAMOLECULAR) 75 NH DIPOLAR COULINGS FOR N-TIMP-1, 19 NH DIPOLAR COUPLINGS AND 8 CaHa DIPOLAR COUPLINGS FOR MMP-3 WERE USED FOR REFINEMENT. TARGET FUNCTIONS INCLUDE TERMS FOR NOE RESTRAINTS, DIPOLAR COUPLING RESTRAINTS AND RADIUS OF GYRATION. ALSO, MODULE ( DOSSET ET AL. J. BIOMOL. NMR, (2001),20,223-231) AND PALES (ZWECKSTETTER AND BAX, J. AM. CHEM. SOC (2000), 122, 3791-3792) WERE USED FOR EVALUATING THE ORIENTATION AND STRUCTURES.

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.
