引用ジャーナル : IUCrJ / 年 : 2023タイトル : Analysis of the conformational heterogeneity of the Rieske iron-sulfur protein in complex III by cryo-EM.著者 : Jan Philip Wieferig / Werner Kühlbrandt / 要旨 : Movement of the Rieske domain of the iron-sulfur protein is essential for intramolecular electron transfer within complex III (CIII) of the respiratory chain as it bridges a gap in the cofactor chain ... Movement of the Rieske domain of the iron-sulfur protein is essential for intramolecular electron transfer within complex III (CIII) of the respiratory chain as it bridges a gap in the cofactor chain towards the electron acceptor cytochrome c. We present cryo-EM structures of CIII from Yarrowia lipolytica at resolutions up to 2.0 Å under different conditions, with different redox states of the cofactors of the high-potential chain. All possible permutations of three primary positions were observed, indicating that the two halves of the dimeric complex act independently. Addition of the substrate analogue decylubiquinone to CIII with a reduced high-potential chain increased the occupancy of the Q site. The extent of Rieske domain interactions through hydrogen bonds to the cytochrome b and cytochrome c subunits varied depending on the redox state and substrate. In the absence of quinols, the reduced Rieske domain interacted more closely with cytochrome b and cytochrome c than in the oxidized state. Upon addition of the inhibitor antimycin A, the heterogeneity of the cd-helix and ef-loop increased, which may be indicative of a long-range effect on the Rieske domain. 履歴 登録 2022年7月5日 登録サイト : PDBE / 処理サイト : PDBE改定 1.0 2023年1月11日 Provider : repository / タイプ : Initial release改定 1.1 2023年1月25日 Group : Database references / Structure summary / カテゴリ : audit_author / citation / citation_authorItem : _audit_author.name / _citation.journal_volume ... _audit_author.name / _citation.journal_volume / _citation.page_first / _citation.page_last / _citation.pdbx_database_id_DOI / _citation.pdbx_database_id_PubMed / _citation.title / _citation_author.identifier_ORCID 改定 1.2 2024年11月13日 Group : Data collection / Refinement description / Structure summaryカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / em_admin / pdbx_entry_details / pdbx_modification_feature / struct_ncs_dom_lim Item : _em_admin.last_update / _pdbx_entry_details.has_protein_modification ... _em_admin.last_update / _pdbx_entry_details.has_protein_modification / _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
