We previously reported that some carbohydrate hydrolases of Eisenia fetida showed the high activities in cold conditions. In addition, the endo-1,4-beta-glucanase and raw starch-digesting amylases, chitinase and beta-1,4-mannanase gene from E. fetida were cloned, expressed in Pichia pastoris (1, 2, 3, 4). The crystal structures of beta-1,4-glucanase and raw starch-digesting amylase (EF-AmyI) and beta-1,4-mannanase have been already analyzed (4, 5, 6). The negatively charged amino acids (Asp and Glu) of beta-1,4-glucanase (EF-EG2) occupied over two-thirds of accessible surface area from the total charged amino acids. It seems that the highly negatively charged surface of EF-EG2 contributes to the cold adaptation. We have applied site-directed mutagenesis (mutation of salt bridges) to improve the catalytic efficiency of beta-1,4-mannnanase at cold condition. It found that salt bridge formed by R318 played an important role for the increase of catalytic activity at low temperature condition.", "subitem_description_type": "Abstract"}]}, "item_10005_description_6": {"attribute_name": "会議概要（会議名, 開催地, 会期, 主催者等）", "attribute_value_mlt": [{"subitem_description": "14th International Chitin and Chitosan Conference ", "subitem_description_type": "Other"}]}, "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": "中, 裕規"}], "nameIdentifiers": [{"nameIdentifier": "718501", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "平野, 優"}], "nameIdentifiers": [{"nameIdentifier": "718502", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中澤, 昌美"}], "nameIdentifiers": [{"nameIdentifier": "718503", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "阪本, 龍司"}], "nameIdentifiers": [{"nameIdentifier": "718504", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "玉田, 太郎"}], "nameIdentifiers": [{"nameIdentifier": "718505", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "上田, 光宏"}], "nameIdentifiers": [{"nameIdentifier": "718506", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "平野 優", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "718507", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "玉田 太郎", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "718508", "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": "conference object", "resourceuri": "http://purl.org/coar/resource_type/c_c94f"}]}, "item_title": "Structural and functional analysis of carbohydrate hydrolases from Eisenia fetida ", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Structural and functional analysis of carbohydrate hydrolases from Eisenia fetida "}]}, "item_type_id": "10005", "owner": "1", "path": ["28"], "permalink_uri": "https://repo.qst.go.jp/records/72916", "pubdate": {"attribute_name": "公開日", "attribute_value": "2018-09-04"}, "publish_date": "2018-09-04", "publish_status": "0", "recid": "72916", "relation": {}, "relation_version_is_last": true, "title": ["Structural and functional analysis of carbohydrate hydrolases from Eisenia fetida "], "weko_shared_id": -1}
