Title: Substrate processing by the Cdc48 ATPase complex is initiated by ubiquitin unfolding.

Abstract: The Cdc48 adenosine triphosphatase (ATPase) (p97 or valosin-containing protein in mammals) and its cofactor Ufd1/Npl4 extract polyubiquitinated proteins from membranes or macromolecular complexes for ...The Cdc48 adenosine triphosphatase (ATPase) (p97 or valosin-containing protein in mammals) and its cofactor Ufd1/Npl4 extract polyubiquitinated proteins from membranes or macromolecular complexes for subsequent degradation by the proteasome. How Cdc48 processes its diverse and often well-folded substrates is unclear. Here, we report cryo-electron microscopy structures of the Cdc48 ATPase in complex with Ufd1/Npl4 and polyubiquitinated substrate. The structures show that the Cdc48 complex initiates substrate processing by unfolding a ubiquitin molecule. The unfolded ubiquitin molecule binds to Npl4 and projects its N-terminal segment through both hexameric ATPase rings. Pore loops of the second ring form a staircase that acts as a conveyer belt to move the polypeptide through the central pore. Inducing the unfolding of ubiquitin allows the Cdc48 ATPase complex to process a broad range of substrates.

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.
