引用ジャーナル : Nat Commun / 年 : 2020タイトル : Key role of quinone in the mechanism of respiratory complex I.著者 : Javier Gutiérrez-Fernández / Karol Kaszuba / Gurdeep S Minhas / Rozbeh Baradaran / Margherita Tambalo / David T Gallagher / Leonid A Sazanov / 要旨 : Complex I is the first and the largest enzyme of respiratory chains in bacteria and mitochondria. The mechanism which couples spatially separated transfer of electrons to proton translocation in ... Complex I is the first and the largest enzyme of respiratory chains in bacteria and mitochondria. The mechanism which couples spatially separated transfer of electrons to proton translocation in complex I is not known. Here we report five crystal structures of T. thermophilus enzyme in complex with NADH or quinone-like compounds. We also determined cryo-EM structures of major and minor native states of the complex, differing in the position of the peripheral arm. Crystal structures show that binding of quinone-like compounds (but not of NADH) leads to a related global conformational change, accompanied by local re-arrangements propagating from the quinone site to the nearest proton channel. Normal mode and molecular dynamics analyses indicate that these are likely to represent the first steps in the proton translocation mechanism. Our results suggest that quinone binding and chemistry play a key role in the coupling mechanism of complex I. 履歴 登録 2020年2月10日 登録サイト : PDBE / 処理サイト : PDBE改定 1.0 2020年9月2日 Provider : repository / タイプ : Initial release改定 1.1 2024年1月24日 Group : Data collection / Database references / Refinement descriptionカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / database_2 / pdbx_initial_refinement_model / struct_ncs_dom_lim Item : _database_2.pdbx_DOI / _database_2.pdbx_database_accession ... _database_2.pdbx_DOI / _database_2.pdbx_database_accession / _struct_ncs_dom_lim.beg_auth_comp_id / _struct_ncs_dom_lim.beg_label_asym_id / _struct_ncs_dom_lim.beg_label_comp_id / _struct_ncs_dom_lim.beg_label_seq_id / _struct_ncs_dom_lim.end_auth_comp_id / _struct_ncs_dom_lim.end_label_asym_id / _struct_ncs_dom_lim.end_label_comp_id / _struct_ncs_dom_lim.end_label_seq_id 改定 1.2 2024年10月23日 Group : Structure summaryカテゴリ : pdbx_entry_details / pdbx_modification_featureItem : _pdbx_entry_details.has_protein_modification
