Nonpolymer detailsIn both subunits the cofactor pyridoxal-5'-phosphate forms a covalent adduct with the inhibitor ...In both subunits the cofactor pyridoxal-5'-phosphate forms a covalent adduct with the inhibitor amiclenomycin, followed by aromatization of amiclenomycin hexadiene ring. The binding mode for the inhibitor is different in the two subunits. The electron density for the covalent adduct between amiclenomycin and pyridoxal-5'-phosphate is better in monomer A. For details see the primary citation.

In monomer B three stretches of residues are disordered, 159-168, 180-189 and 299-303 resp. Residue 429 was excluded from both monomers. A number of side chains on the surface of the protein are disordered. The occupancy for these is estimated to 0 in most cases. In four cases the side chains are given the occupancy 0.5.

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.
