The results of the urea-induced unfolding transition show that GroEL partially dissociates in the presence of more than 2 M urea, cooperatively unfolds at around 3 M urea, and is in a monomeric random coil-like unfolded structure at more than 3.2 M urea. Attempted refolding of the unfolded GroEL monomer by a simple dilution procedure is not successful, leading to formation of aggregates. However, the presence of ammonium sulfate and MgADP allows the fully unfolded GroEL to refold into a structure with the same hydrodynamic dimension, within experimental error, as that of the native GroEL. Moreover, the X-ray scattering profiles of the GroEL thus refolded and the native GroEL are coincident with each other, showing that the refolded GroEL has the same structure and the molecular mass as the native GroEL. These results demonstrate that the fully unfolded GroEL monomer can refold and reassemble into the native tetradecameric structure in the presence of ammonium sulfate and MgADP without ATP hydrolysis and preexisting chaperones. Therefore, GroEL can, in principle, fold and assemble into the native structure according to the intrinsic characteristic of its polypeptide chain, although preexisting GroEL would be important when the GroEL folding takes place under in vivo conditions, in order to avoid misfolding and aggregation.", "subitem_description_type": "Abstract"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Wiley "}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "10.1110/ps.0233603"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1110/ps.0233603", "subitem_relation_type_select": "DOI"}}]}, "item_10001_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2003 The Protein Society"}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0961-8368", "subitem_source_identifier_type": "ISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "metadata only access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_14cb"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "ARAI, Munehito"}], "nameIdentifiers": [{"nameIdentifier": "2491", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KUWAJIMA, Kunihiro "}], "nameIdentifiers": [{"nameIdentifier": "2361", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "et, al."}], "nameIdentifiers": [{"nameIdentifier": "3119", "nameIdentifierScheme": "WEKO"}]}]}, "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": "Denaturation and reassembly of chaperonin GroEL studied by solution X-ray scattering", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Denaturation and reassembly of chaperonin GroEL studied by solution X-ray scattering"}, {"subitem_title": "Denaturation and reassembly of chaperonin GroEL studied by solution X-ray scattering", "subitem_title_language": "en"}]}, "item_type_id": "10001", "owner": "21", "path": ["323"], "permalink_uri": "https://ir.soken.ac.jp/records/4314", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-03-19"}, "publish_date": "2014-03-19", "publish_status": "0", "recid": "4314", "relation": {}, "relation_version_is_last": true, "title": ["Denaturation and reassembly of chaperonin GroEL studied by solution X-ray scattering"], "weko_shared_id": 21}
