  • Saponin-digesting enzymes, genes thereof and soyasapogenol B mass production system
    Patent number: 7022508
    Abstract: 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.
