EM reconstructions of the Drosophila melanogaster origin recognition complex ...Structural details of initiator proteins for DNA replication have provided clues to the molecular events in this process. EM reconstructions of the Drosophila melanogaster origin recognition complex (ORC) reveal nucleotide-dependent conformational changes in the core of the complex. All five AAA+ domains in ORC contain a conserved structural element that, in DnaA, promotes formation of a right-handed helix, indicating that helical AAA+ substructures may be a feature of all initiators. A DnaA helical pentamer can be docked into ORC, and the location of Orc5 uniquely positions this core. The results suggest that ATP-dependent conformational changes observed in ORC derive from reorientation of the AAA+ domains. By analogy to the DNA-wrapping activity of DnaA, we posit that ORC together with Cdc6 prepares origin DNA for helicase loading through mechanisms related to the established pathway of prokaryotes.

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.
