Diheme-containing succinate:menaquinone oxidoreductases (Sdh) are widespread in Gram-positive bacteria but little is known about the catalytic mechanisms they employ for succinate oxidation by menaquinone. Here, we present the 2.8 Å cryo-electron microscopy structure of a Mycobacterium smegmatis Sdh, which forms a trimer. We identified the membrane-anchored SdhF as a subunit of the complex. The 3 kDa SdhF forms a single transmembrane helix and this helix plays a role in blocking the canonically proximal quinone-binding site. We also identified two distal quinone-binding sites with bound quinones. One distal binding site is formed by neighboring subunits of the complex. Our structure further reveals the electron/proton transfer pathway for succinate oxidation by menaquinone. Moreover, this study provides further structural insights into the physiological significance of a trimeric respiratory complex II. The structure of the menaquinone binding site could provide a framework for the development of Sdh-selective anti-mycobacterial drugs. 履歴 登録 2020年1月29日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2020年5月27日 Provider : repository / タイプ : Initial release改定 1.1 2020年10月7日 Group : Database references / Derived calculations / カテゴリ : citation / citation_author / struct_connItem : _citation.country / _citation.journal_abbrev ... _citation.country / _citation.journal_abbrev / _citation.journal_id_CSD / _citation.journal_id_ISSN / _citation.journal_volume / _citation.page_first / _citation.page_last / _citation.pdbx_database_id_DOI / _citation.pdbx_database_id_PubMed / _citation.title / _citation.year / _struct_conn.ptnr1_auth_asym_id / _struct_conn.ptnr1_auth_comp_id / _struct_conn.ptnr1_auth_seq_id / _struct_conn.ptnr1_label_asym_id / _struct_conn.ptnr1_label_atom_id / _struct_conn.ptnr1_label_comp_id / _struct_conn.ptnr1_label_seq_id / _struct_conn.ptnr2_auth_asym_id / _struct_conn.ptnr2_auth_comp_id / _struct_conn.ptnr2_auth_seq_id / _struct_conn.ptnr2_label_asym_id / _struct_conn.ptnr2_label_atom_id / _struct_conn.ptnr2_label_comp_id / _struct_conn.ptnr2_label_seq_id 改定 2.0 2020年12月2日 Group : Advisory / Atomic model ...
