Title: Cryo-EM structures reveal the acetylation process of piccolo NuA4.
Authors: Lin Wang / Haonan Zhang / Qi Jia / Wenyan Li / Chenguang Yang / Lijuan Ma / Ming Li / Ying Lu / Hongtao Zhu / Ping Zhu /
Abstract: NuA4 is the only essential acetyltransferase in yeast that can catalyze the acetylation of the histones H2A, H2A.Z, and H4, thereby affecting gene transcription. However, the acetylation process of ...NuA4 is the only essential acetyltransferase in yeast that can catalyze the acetylation of the histones H2A, H2A.Z, and H4, thereby affecting gene transcription. However, the acetylation process of NuA4, such as how NuA4 acetylates H4 and H2A.Z differently, remains largely elusive. Here, using cryoelectron microscopy (cryo-EM) single particle analysis, we present seven cryo-EM structures of piccolo NuA4 (pNuA4) in complex with wild-type H2A.Z or H2A.Z-mutant-containing nucleosomes in the absence or presence of acetyl coenzyme A (Ac-CoA). We revealed that, in the absence of Ac-CoA, pNuA4 adopts multiple conformations to search for its substrates. After adding Ac-CoA, the single-molecule Förster resonance energy transfer (smFRET) and cryo-EM data indicated that pNuA4 prefers to bind H4 and undergoes a dynamic conformational change to complete the acetylation. We also obtained previously unseen structures in states associated with the acetylation of H2A.Z. These cryo-EM structures and smFRET results suggest a complex acetylation process on H4 and H2A.Z by pNuA4. The results provide a comprehensive picture of the mechanism by which pNuA4 acetylates its substrates within an H2A.Z-containing nucleosome.

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.
