Biochemical studies have found a divide in the behavior of complex I in metazoans that aligns with the evolutionary split between Protostomia and Deuterostomia. Complex I from Deuterostomia including mammals can adopt a biochemically defined off-pathway 'deactive' state, whereas complex I from Protostomia cannot. The presence of off-pathway states complicates the interpretation of structural results and has led to considerable mechanistic debate. Here, we report the structure of mitochondrial complex I from the thoracic muscles of the model protostome . We show that although complex I (-CI) does not have a NEM-sensitive deactive state, it does show slow activation kinetics indicative of an off-pathway resting state. The resting-state structure of -CI from the thoracic muscle reveals multiple conformations. We identify a helix-locked state in which an N-terminal α-helix on the NDUFS4 subunit wedges between the peripheral and membrane arms. Comparison of the -CI structure and conformational states to those observed in bacteria, yeast, and mammals provides insight into the roles of subunits across organisms, explains why the -CI off-pathway resting state is NEM insensitive, and raises questions regarding current mechanistic models of complex I turnover. 履歴 登録 2022年10月15日 - ヘッダ(付随情報) 公開 2023年3月29日 - マップ公開 2023年3月29日 - 更新 2023年4月5日 - 現状 2023年4月5日 処理サイト : RCSB / 状態 : 公開
