摘要: [Problem]
To provide an improved β-fructofuranosidase which enables the production of kestose with high efficiency while reducing the amount of a by-product such as nystose produced during the production of kestose.
[Solution]
An improved β-fructofuranosidase comprising an amino acid sequence which is produced by introducing an amino acid mutation into an amino acid sequence for a β-fructofuranosidase having 60% or higher identity to the amino acid sequence for wild-type β-fructofuranosidase which is represented by SEQ ID NO: 2, wherein the amino acid mutation is such a mutation that, when amino acid sequence alignment is performed, a histidine (H) residue corresponding to the position as numbered from the N-terminal of the amino acid sequence for the wild-type β-fructofuranosidase which is represented by SEQ ID NO: 2 can be replaced by an arginine (R) residue or a lysine (K) residue.摘要翻译: [问题]提供改进的β-呋喃果糖苷酶,其能够高效率地生产睾丸酮,同时减少副产物的量,例如在生产睾丸酮期间产生的糖。 [解决方案]改进的β-呋喃果糖苷酶包含通过将氨基酸突变引入氨基酸序列而产生的氨基酸序列,所述氨基酸序列与野生型呋喃果糖苷酶的氨基酸序列具有60%或更高同一性的2-呋喃果糖苷酶 其由SEQ ID NO:2表示,其中氨基酸突变是这样的突变,当进行氨基酸序列比对时,对应于氨基酸的N末端的位置的组氨酸(H)残基 由SEQ ID NO:2表示的野生型2-呋喃果糖苷酶的序列可以被精氨酸(R)残基或赖氨酸(K)残基所代替。

摘要: [Problem]
To provide an improved β-fructofuranosidase which is capable of efficiently producing kestose while inhibiting the production of nystose.
[Solution]
This improved β-fructofuranosidase comprises either: an amino acid sequence (a) obtained by introducing, into the amino acid sequence represented by SEQ ID NO: 2, an amino acid mutation i) in which the 85th glycine (G) from the N-terminal is substituted for a protein-constituting amino acid other than glycine (G), and/or an amino acid mutation ii) in which the 310th histidine (H) from the N-terminal is substituted for lysine (K), arginine (R), or tyrosine (Y); or an amino acid sequence (b) which exhibits β-fructofuranosidase activity, and which comprises an amino acid sequence obtained by deleting, substituting, inserting, or adding one or more amino acids in (a) other than the amino acid into which the amino acid mutation has been introduced.摘要翻译: 本发明提供一种能够在抑制芽孢杆菌生成的同时有效地生产酮酯糖的改良型β-呋喃果糖苷酶。 该改良的β-呋喃果糖苷酶含有:在序列号2所示的氨基酸序列中导入了来自第85位的甘氨酸(G)的氨基酸突变i) N-末端取代除甘氨酸(G)以外的蛋白质构成氨基酸,和/或ii)来自N-末端的第310个组氨酸(H)取代赖氨酸(K)的氨基酸突变ii) 精氨酸(R)或酪氨酸(Y); 或显示β-呋喃果糖苷酶活性的氨基酸序列(b),并且包含通过缺失,取代,插入或添加(a)中的一个或多个氨基酸而获得的氨基酸序列,所述氨基酸不同于氨基酸 酸性突变已被引入。
