Title: Nucleosome spacing regulates linker methylation by DNMT3A2/3B3.

Abstract: De novo CpG methylation (mCpG) is deposited by DNMT3A and DNMT3B, which target DNA linkers between nucleosomes. Cells contain millions of unique linkers, but the rules dictating which linkers get ...De novo CpG methylation (mCpG) is deposited by DNMT3A and DNMT3B, which target DNA linkers between nucleosomes. Cells contain millions of unique linkers, but the rules dictating which linkers get targeted by DNMT3 enzymes are not understood. We show that nucleosome spacing controls linker DNA methylation and H3K36me2 recognition by human DNMT3A2/3B3, linking de novo methylation to chromatin architecture. We present structures of DNMT3A2/3B3 bound to dinucleosomes, revealing that short linkers promote dinucleosome bridging, blocking access to linker DNA and suppressing methylation, whereas long linkers allow DNMT3A2/3B3 to engage each nucleosome separately and methylate linker DNA. Finally, we show that DNMT3A2/3B3 positions proline-tryptophan-tryptophan-proline (PWWP) domains to scan for H3K36me2. However, H3K36me2 recognition is blocked when DNMT3A2/3B3 bridges dinucleosomes with short linkers, imposing an additional structural constraint on DNMT3A2/3B3 function. Together, these findings uncover the mechanisms that govern de novo methylation in chromatin and explain how DNMT3 enzymes target linkers in 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.
