Title: Structural basis of transcription-coupled RNA damage by incorporation of oxidized ribonucleotides.
Authors: Peini Hou / Chanjoo Lee / Jenny Chong / Juntaek Oh / Dong Wang /
Abstract: Oxidative stress induces damage to DNA, RNA, and nucleotide pools. Unlike well-studied DNA damage, the formation of RNA damage and the impact of an oxidized ribonucleotide pool on transcription ...Oxidative stress induces damage to DNA, RNA, and nucleotide pools. Unlike well-studied DNA damage, the formation of RNA damage and the impact of an oxidized ribonucleotide pool on transcription fidelity are poorly understood. Here, we investigate the structural basis of transcription-coupled RNA damage and the effect of 8-oxo-guanosine triphosphate (8-oxo-rGTP) on RNA polymerase II (Pol II) transcription fidelity control steps. We revealed that the incorporation efficiency of 8-oxo-rGTP opposite a dC template is comparable to that of GTP. In contrast, the incorporation efficiency of 8-oxo-rGTP opposite a dA template is ~150-fold more efficient than that of GTP. For the extension step, Pol II extends substantially faster from a 3'-8-oxo-rG:dC base pair than from a 3'-8-oxo-rG:dA base pair. For the proofreading step, strikingly, Pol II EC with 3'-8-oxo-rG:dA base pair is much more resistant to backtracking and proofreading than Pol II EC with 3'-8-oxo-rG:dC base pair. Using X-ray crystallography, we revealed that 8-oxo-rGTP adopts different prechemistry binding sites depending on whether it is paired with a dC or a dA template. Upon incorporation, the nucleobase of 8-oxo-rG flips to the -conformation to form a Hoogsteen pair with a dA template, whereas it remains in the -conformation to form a Watson-Crick pair with a dC template. Collectively, our work demonstrates that nucleotide-pool oxidation can directly affect Pol II fidelity control steps and elongation dynamics and induce RNA damage in a transcription-coupled manner.

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

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.
