皂苷分解酶，其基因和大规模生产大豆皂甙B的生产系统

Saponin-decomposing enzyme, gene thereof and large-scale production sytem for producing soyasapogenol B
摘要：
The present invention provides a protein having saponin-decomposing activity, more specifically a protein which can decompose a glycoside having soyasapogenol B as an aglycone to produce soyasapogenol B, a polynucleotide encoding such a protein, and a method of producing soyasapogenol B on a large scale using the same. A protein according to the present invention are concerned with (a), (b) or (c), namely (a) a protein comprising an amino acid sequence selected from the group consisting of the amino acid sequences shown in SEQ ID NOs: 2, 4, and 6; (b) a protein that has at least 50% homology to the protein comprising the amino acid sequence of the sequence described in (a) and having saponin-decomposing activity; or (c) a protein comprising a modified amino acid sequence of the sequence described in (a) that has one or more amino acid residues deleted, substituted, inserted, or added and having saponin-decomposing activity.
摘要（中）：

本发明提供具有皂苷分解活性的蛋白质，更具体地说，可以分解具有大豆皂甙元酚B作为糖苷配基的糖苷以制备大豆皂甙元B的蛋白质，编码这种蛋白质的多核苷酸以及大规模生产大豆皂甙元B的方法的蛋白质 使用相同 根据本发明的蛋白质涉及（a），（b）或（c），即（a）包含选自SEQ ID NO：2所示的氨基酸序列的氨基酸序列的蛋白质 ，4和6; （b）与包含（a）中所述序列的氨基酸序列并且具有皂苷分解活性的蛋白质具有至少50％同源性的蛋白质; 或（c）包含（a）中描述的具有一个或多个氨基酸残基被缺失，取代，插入或添加并具有皂苷分解活性的修饰的氨基酸序列的蛋白质。
