Abstract
(EN) Provided are a glucose dehydrogenase originating in Botryotinia fuckeliana, a method for producing the same, and an assay method, a reagent composition and a biosensor each using the aforesaid enzyme. A biosensor for assaying glucose without being affected by dissolved oxygen, characterized by using a flavin-bound glucose dehydrogenase that comprises glycopolypeptide (e) or (f): (e) a glycopolypeptide comprising an amino acid sequence represented by SEQ ID NO:5; and (f) a glycopolypeptide comprising an amino acid sequence that is derived from the amino acid sequence represented by SEQ ID NO:5 by substitution, deletion or addition of one to several amino acids and having glucose dehydrogenase activity.
(FR) L'invention concerne une glucose déshydrogénase provenant de Botryotinia fuckeliana, un procédé de production de celle-ci, et une méthode de dosage, une composition de réactif et un biocapteur, utilisant chacun l'enzyme mentionnée ci-dessus. L'invention concerne un biocapteur pour le dosage du glucose sans être affecté par l'oxygène dissous, caractérisé en ce qu'il utilise une glucose déshydrogénase liée à une flavine qui comprend un glycopolypeptide (e) ou (f) : (e) un glycopolypeptide comprenant une séquence d'acides aminés représentée par SEQ ID No:5 ; et (f) un glycopolypeptide comprenant une séquence d'acides aminés qui est issue de la séquence d'acides aminés représentée par SEQ ID No:5 par substitution, délétion ou addition d'un à plusieurs acides aminés et ayant une activité glucose déshydrogénase.
(JA)  ボトリオティニア・フケリアナ由来のグルコース脱水素酵素及びその製造方法、並びに該酵素を用いた測定方法、試薬組成物及びバイオセンサを提供するものである。 以下の(e)又は(f)の糖ポリペプチドからなるフラビン結合型グルコース脱水素酵素を使用することを特徴とする、溶存酸素の影響を受けないグルコース測定用バイオセンサ: (e)配列番号5で示されるアミノ酸配列からなる糖ポリペプチド、 (f)配列番号5で示されるアミノ酸配列において1~数個のアミノ酸が置換、欠失又は付加されたアミノ酸配列からなり、かつグルコース脱水素酵素活性を有する糖ポリペプチド。
