| 摘要 |
The present invention relates to Rhodanobacter ginsenosidimutans KCTC22231T-derived ginsenoside glycosidase and use thereof, and this protein has an activity of converting PPD (protopanaxadiol)-type saponins into in vivo absorbable, highly active deglycosylated saponins by selective hydrolysis of a bond at a particular position of ginsenoside. More particularly, the present invention relates to an amino acid sequence constituting the protein, a nucleic acid sequence encoding the protein, a recombinant vector comprising the nucleic acid sequence, a transformant transformed with the vector, a method for preparing Rhodanobacter ginsenosidimutans KCTC22231T-derived ginsenoside glycosidase by culturing the transformant, a method for converting PPD (protopanaxadiol)-type major ginsenoside into a rare ginsenoside that is absorbable in vivo using the protein, and a composition for converting PPD-type saponins into in vivo absorbable saponins, comprising the protein as an active ingredient.
