Recent analyses have indicated that conventional refinement methods do not always provide accurate models of crystallographic heterogeneities and that some information on polymorphism has been overlooked in previous crystallographic studies. In the present study, the m|Fo|   D|Fc| electron-density maps of double-helical DNA crystal structures were calculated at a resolution equal to or better than 1.5 A ˚ and potential conformational transitions were found in 27% of DNA phosphates. Detailed analyses of the m|Fo|   D|Fc| peaks indicated that some of these unassigned densities correspond to ZI $ ZII or A/B ! BI conformational transitions. A relationship was also found between ZI/ZII transitions and metal coordination in Z-DNA from the detected peaks. The present study highlights that frequent transitions of phosphate backbones occur even in crystals and that some of these transitions are affected by the local molecular environment.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1107/S2059798317007707","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2059-7983","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":"Sunami, Tomoko"}],"nameIdentifiers":[{"nameIdentifier":"488956","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Chatake, Toshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"488957","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kono, Hidetoshi"}],"nameIdentifiers":[{"nameIdentifier":"488958","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"角南 智子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"488959","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河野 秀俊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"488960","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":"DNA conformational transitions inferred from reevaluation of  m|Fo|-D|Fc| electron density maps","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"DNA conformational transitions inferred from reevaluation of  m|Fo|-D|Fc| electron density maps"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-03-23"},"publish_date":"2018-03-23","publish_status":"0","recid":"48621","relation_version_is_last":true,"title":["DNA conformational transitions inferred from reevaluation of  m|Fo|-D|Fc| electron density maps"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:26:08.427097+00:00"}
