PubMed AbstractDNA double-strand breaks (DSBs), generated by ionizing radiation, reactive oxygen species and DNA replication across nicks, are the most severe DNA damage in eukaryotic cells. Non-Homologous End ...DNA double-strand breaks (DSBs), generated by ionizing radiation, reactive oxygen species and DNA replication across nicks, are the most severe DNA damage in eukaryotic cells. Non-Homologous End Joining repairs DNA double-strand breaks directly without a template and so can take place at any point in the cell cycle. Ku70/80 heterodimers rapidly assemble around broken DNA ends, allowing DNA-PKcs, the catalytic subunit of DNA-dependent protein kinase, to be recruited and facilitating synapsis of broken DNA ends. This then provides a stage for end-processing and ligation. Here we review progress leading in 2017 to the medium resolution X-ray structure of DNA-PKcs, a single polypeptide chain of 4128 amino acids. This was followed quickly by chain tracing of cryo-EM structures of DNA-PKcs in complex with Ku and DNA. We discuss how combination of structural information from X-ray and cryo-EM studies can produce a working model for complex multicomponent molecular assemblies such as those found in DNA-double-strand-break repair.

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.
