Here, we report a series of cryo-EM structures of the substrate-engaged human p97 complex with resolutions ranging from 2.9 to 3.8 Å that captured 'power-stroke'-like motions of both the D1 and D2 ATPase rings of p97. A key feature of these structures is the critical conformational changes of the intersubunit signaling (ISS) motifs, which tighten the binding of nucleotides and neighboring subunits and contribute to the spiral staircase conformation of the D1 and D2 rings. In addition, we determined the cryo-EM structure of human p97 in complex with NMS-873, a potent p97 inhibitor, at a resolution of 2.4 Å. The structures showed that NMS-873 binds at a cryptic groove in the D2 domain and interacts with the ISS motif, preventing its conformational change and thus blocking substrate translocation allosterically. 履歴 登録 2021年2月6日 - ヘッダ(付随情報) 公開 2021年9月15日 - マップ公開 2021年9月15日 - 更新 2024年5月29日 - 現状 2024年5月29日 処理サイト : RCSB / 状態 : 公開
