引用ジャーナル : Elife / 年 : 2018タイトル : Structural principles of SNARE complex recognition by the AAA+ protein NSF.著者 : K Ian White / Minglei Zhao / Ucheor B Choi / Richard A Pfuetzner / Axel T Brunger / 要旨 : The recycling of SNARE proteins following complex formation and membrane fusion is an essential process in eukaryotic trafficking. A highly conserved AAA+ protein, NSF (-ethylmaleimide sensitive ... The recycling of SNARE proteins following complex formation and membrane fusion is an essential process in eukaryotic trafficking. A highly conserved AAA+ protein, NSF (-ethylmaleimide sensitive factor) and an adaptor protein, SNAP (soluble NSF attachment protein), disassemble the SNARE complex. We report electron-cryomicroscopy structures of the complex of NSF, αSNAP, and the full-length soluble neuronal SNARE complex (composed of syntaxin-1A, synaptobrevin-2, SNAP-25A) in the presence of ATP under non-hydrolyzing conditions at ~3.9 Å resolution. These structures reveal electrostatic interactions by which two αSNAP molecules interface with a specific surface of the SNARE complex. This interaction positions the SNAREs such that the 15 N-terminal residues of SNAP-25A are loaded into the D1 ring pore of NSF via a spiral pattern of interactions between a conserved tyrosine NSF residue and SNAP-25A backbone atoms. This loading process likely precedes ATP hydrolysis. Subsequent ATP hydrolysis then drives complete disassembly. 履歴 登録 2018年9月4日 - ヘッダ(付随情報) 公開 2018年9月19日 - マップ公開 2018年9月19日 - 更新 2024年3月13日 - 現状 2024年3月13日 処理サイト : RCSB / 状態 : 公開
