Abstract: In mammalian global genomic nucleotide excision repair, UV-DDB plays a central role in recognizing DNA lesions, such as 6-4 photoproducts and cyclobutane pyrimidine dimers, within chromatin. In the ...In mammalian global genomic nucleotide excision repair, UV-DDB plays a central role in recognizing DNA lesions, such as 6-4 photoproducts and cyclobutane pyrimidine dimers, within chromatin. In the present study, we perform cryo-electron microscopy analyses coupled with chromatin-immunoprecipitation to reveal that the cellular UV-DDB binds to UV-damaged DNA lesions in a chromatin unit, the nucleosome, at a position approximately 20 base-pairs from the nucleosomal dyad in human cells. An alternative analysis of the in vitro reconstituted UV-DDB-cyclobutane pyrimidine dimer nucleosome structure demonstrates that the DDB2 subunit of UV-DDB specifically recognizes the cyclobutane pyrimidine dimer lesion at this position on the nucleosome. We also determine the structures of UV-DDB bound to DNA lesions at other positions in purified cellular human nucleosomes. These cellular and reconstituted UV-DDB-nucleosome complex structures provide important evidence for understanding the mechanism by which UV lesions in chromatin are recognized and repaired in mammalian cells.

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.
