In the present study, we attempted to purify inulinase P-I from Aspergillus niger by ion-exchange chromatography in DEAE-Cellulose column and gel filtration in Sephadex column. The catalytic properties of this electrophoretically homogeneous enzyme were compared with those of inulinase P-II described in the previous report. The molecular weight of P- I was estimated to be 72,000 and 70,000 by Sephadex G-200 gel chromatography and SDS-PAGE, respectively, suggesting that P-I is a monomer enzyme. The optimum pH was 4.0 for P-I and 5.0 for P-II and the optimum temperature was nearly 50t for both enzymes. Either of the two was stable within the range of pH 4.0-7.0 and the activity was not affected by heat treatment at 50°C. Further, both enzymes exhibited specific activities to inulin, sucrose and raffinose, but not to levan and melezitose. The values of Km for inulin and sucrose were 0.40 and 7.14 mM for P-I, and 1.87 and 12.50 mM for P- II. Next, the effects of metal ions and inhibitors on the activities of P-I and P-II were investigated. Mn^2+ ion activated the both enzymes and Ag^+ and Hg^2+ ions showed nearly complete inhibition of them. In addition, Fe^3+ and PCMB had strong inhibitory effects on the both enzymes and only P-I was slightly resistant to the inhibition of EDTA.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学農学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Miyazaki University","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00236503","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05446066","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中村, 豊彦","creatorNameLang":"ja"},{"creatorName":"ナカムラ, トヨヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"Nakamura, Toyohiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"浦川, 智博","creatorNameLang":"ja"},{"creatorName":"ウラカワ, トモヒロ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"水光, 正仁","creatorNameLang":"ja"},{"creatorName":"スイコウ, マサヒト","creatorNameLang":"ja-Kana"},{"creatorName":"Suiko, Masahito","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"太田, 一良","creatorNameLang":"ja"},{"creatorName":"オオタ, カズヨシ","creatorNameLang":"ja-Kana"},{"creatorName":"Ohta, Kazuyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Urakawa, Tomohiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"oota_1.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"oota_1.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/3226/files/oota_1.pdf"},"version_id":"9fc1ab54-a588-48c1-a741-6ab1510132be"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Inulinase, Aspergillus niger, Exo-inulinase, Inulin","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Aspergillus nigerの生産する細胞外エキソ型イヌリナ-ゼ(P-I)の性質について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Aspergillus nigerの生産する細胞外エキソ型イヌリナ-ゼ(P-I)の性質について","subitem_title_language":"ja"},{"subitem_title":"Properties of extracellular inulinase (P-I) from Aspergillus niger","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["74","46","349","367"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-07-05"},"publish_date":"2013-07-05","publish_status":"0","recid":"3226","relation_version_is_last":true,"title":["Aspergillus nigerの生産する細胞外エキソ型イヌリナ-ゼ(P-I)の性質について"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2023-07-30T03:07:48.227850+00:00"}
