Title: CryoEM Strategies for Elucidating the Closed State Architecture of CCT.

Abstract: Cryo-electron microscopy (CryoEM) has emerged as a state-of-the-art technique in structural biology, thanks to advances in sample preparation, high-voltage electron microscopy, direct electron ...Cryo-electron microscopy (CryoEM) has emerged as a state-of-the-art technique in structural biology, thanks to advances in sample preparation, high-voltage electron microscopy, direct electron detectors, and sophisticated image processing software. In this study, we investigate the eukaryotic chaperonin CCT, a ~1 MDa hetero-oligomeric complex essential for the folding of key substrates such as actin, tubulin, and WD40 family members. While several open-state structures of CCT have been resolved, the highest-resolution reconstructions have been obtained in the closed state. This is primarily due to the increased structural rigidity of the complex when its apical domains become immobilized in this conformation. However, the pseudo-symmetric arrangement of subunits in the closed state poses challenges for subunit identification. Here, we present a workflow for obtaining a high-resolution CryoEM structure of closed CCT, achieved without the use of nanobodies, substrates, or any tools designed to increase CCT asymmetry. Our results demonstrate that subunit assignment and atomic modeling are achievable by exploiting subunit-intrinsic structural features alone.

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.
