The magnetosomes have well-ordered chain-like structures, comprising membrane-enveloped, nano-sized magnetic crystals, and various types of specifically associated proteins. In this study, we applied atomic force microscopy (AFM) to investigate the spatial configuration of isolated magnetosomes from AMB-1 in near-native buffer conditions. AFM observation revealed organic material with a ∼7-nm thickness surrounding a magnetite crystal. Small globular proteins, identified as magnetosome-associated protein MamA, were distributed on the mica surface around the magnetosome. Immuno-labeling with AFM showed that MamA is located on the magnetosome surface. In vitro experiments showed that MamA proteins interact with each other and form a high molecular mass complex. These findings suggest that magnetosomes are covered with MamA oligomers in near-native environments. Furthermore, nanodissection revealed that magnetosomes are built with heterogeneous structures that comprise the organic layer. This study provides important clues to the supramolecular architecture of the bacterial organelle, the magnetosome, and insight into the function of the proteins localized in the organelle.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域数物科学系","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00010925","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Academy of Sciences (U.S.)"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1073/pnas.1001870107","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.pnas.org/content/early/2010/04/30/1001870107.abstract","subitem_relation_type_select":"URI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA10808769","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0027-8424","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yamamoto, Daisuke"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Taoka, Azuma"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Uchihashi, Takayuki"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Sasaki, Hideaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Hiroki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ando, Toshio"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Fukumori, Yoshihiro"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"SC-PR-YAMAMOTO-D-2010.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SC-PR-YAMAMOTO-D-2010.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/10938/files/SC-PR-YAMAMOTO-D-2010.pdf"},"version_id":"d60e5775-7022-40df-8541-7e0fcba2c41e"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Visualization and structural analysis of the bacterial magnetic organelle magnetosome using atomic force microscopy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Visualization and structural analysis of the bacterial magnetic organelle magnetosome using atomic force microscopy"}]},"item_type_id":"4","owner":"3","path":["3021"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"10938","relation_version_is_last":true,"title":["Visualization and structural analysis of the bacterial magnetic organelle magnetosome using atomic force microscopy"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T10:30:01.471499+00:00"}
