| abstract |
The present invention relates to a novel ginsenoside glycosidase protein derived from the genus Terrabacter, , the protein having an activity whereby it converts PPD (protopanaxadiol) type saponins into highly active substances, which can be absorbed inside the body, by selectively hydrolysing specific position bonding bonds of ginsenoside.; More specifically, the invention relates to the amino acid sequence of the protein, the nucleic acid sequence coding for the protein, a recombinant vector comprising the nucleic acid sequence, and a transformant transformed by means of the vector, and concerns a method for producing ginsenoside glycosidase derived from the genus Terrabacter by culturing the transformant, a method for converting PPD type major saponins into the minor saponin form by using the protein, and a composition for converting PPD type saponins into soluble saponins which comprises the protein as an active component. |
