The molten globule state of α-lactalbumin has been best characterized, but two major issues have yet to be clarified. At which stage of the kinetic refolding is the molten globule state stably organized? And what is the major driving force that stabilizes the molten globule state? We address these questions in this paper.\n\nResultsWe have investigated the refolding kinetics of α-lactalbumin using stopped-flow CD and fluorescence, acrylamide quenching and pulsed hydrogen exchange NMR techniques. A burst-phase intermediate was observed to form within 15 ms. The intermediate was characterized by pronounced, hydrogen-bonded secondary structure, exposure of hydrophobic surfaces and the absence of tertiary structure. Furthermore, the stability of the secondary structure is the same as that in the equilibrium molten globule state.\n\nConclusionThe burst-phase intermediate in α-lactalbumin refolding is identical with the molten globule state. Two different models, the hydrophobic collapse model and the secondary-structure coalescence model, of protein folding are discussed on the basis of the present results. The importance of solvent-separated hydrophobic interactions that stabilize the molten globule state is proposed.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/S1359-0278(96)00041-7"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/S1359-0278(96)00041-7","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 1996 Elsevier Ltd."}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1359-0278","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":[{}]},{"creatorNames":[{"creatorName":"KUWAJIMA, Kunihiro "}],"nameIdentifiers":[{}]}]},"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":"Rapid formation of a molten globule intermediate in refolding of α-lactalbumin","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Rapid formation of a molten globule intermediate in refolding of α-lactalbumin"},{"subitem_title":"Rapid formation of a molten globule intermediate in refolding of α-lactalbumin","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"21","path":["323"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-03-11"},"publish_date":"2014-03-11","publish_status":"0","recid":"4276","relation_version_is_last":true,"title":["Rapid formation of a molten globule intermediate in refolding of α-lactalbumin"],"weko_creator_id":"21","weko_shared_id":21},"updated":"2023-06-20T14:25:45.090046+00:00"}
