引用 | ジャーナル: FEBS Lett / 年: 2016 タイトル: Nucleotide-dependent conformational changes of the AAA+ ATPase p97 revisited. 著者: Jan M Schuller / Florian Beck / Philip Lössl / Albert J R Heck / Friedrich Förster / 要旨: 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. | |||||||||
