    • Subject matter of the present invention is a modified flavin adenine dinucleotide dependent glucose dehydrogenase or an active fragment thereof that is glycosylated, wherein at least one of the asparagine residues selected from the group consisting of N2; N168 and N346 according to the mature Aspergillus oryzae FAD-GDH wild-type sequence SEQ ID No: 2 (Wild type) has been substituted by one or more amino acids not suitable for glycosylation and thereby eliminating or inactivating, respectively, a potential glycosylation site at this position. Said modified flavin adenine dinucleotide dependent dehydrogenase derived from mature Aspergillus oryzae FAD-GDH wild-type sequence SEQ ID No: 2 (Wild type) or functional fragments thereof have one or more of the following substitutions N2S, N168P, N168SP, and N346D.
    • 本发明的主题是修饰的黄素腺嘌呤二核苷酸依赖性葡萄糖脱氢酶或其糖基化的活性片段,其中至少一种选自N2的天冬酰胺残基; 根据成熟米曲霉FAD-GDH野生型序列SEQ ID No:2(野生型)的N168和N346已被一个或多个不适合糖基化的氨基酸取代,从而分别消除或失活潜在的糖基化位点 在这个位置。 衍生自成熟米曲霉FAD-GDH野生型序列SEQ ID No:2(野生型)或其功能片段的经修饰的黄素腺嘌呤二核苷酸依赖性脱氢酶具有以下取代中的一个或多个取代基N2S,N168P,N168SP和N346D。
