Title: Nucleotide-dependent conformational changes of the AAA+ ATPase p97 revisited.
Authors: Jan M Schuller / Florian Beck / Philip Lössl / Albert J R Heck / Friedrich Förster /
Abstract: The ubiquitous AAA-ATPase p97 segregates ubiquitylated proteins from their molecular environment. Previous studies of the nucleotide-dependent conformational changes of p97 were inconclusive. Here, ...The ubiquitous AAA-ATPase p97 segregates ubiquitylated proteins from their molecular environment. Previous studies of the nucleotide-dependent conformational changes of p97 were inconclusive. Here, we determined its structure in the presence of ADP, AMP-PNP, or ATP-γS at 6.1-7.4 Å resolution using single particle cryo-electron microscopy. Both AAA domains, D1 and D2, assemble into essentially six-fold symmetrical rings. The pore of the D1-ring remains essentially closed under all nucleotide conditions, whereas the D2-ring shows an iris-like opening for ADP. The largest conformational changes of p97 are 'swinging motions' of the N-terminal domains, which may enable segregation of ubiquitylated substrates from their environment.

+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.
