Rare ginsenosides are known to have many medicinal values such as anti-tumor and
anti-oxidant activity. Rare ginsenosides can be obtained by hydrolyzing saponin
glycosides in ginseng with ginsenoside glycosidase. Glycosidases with high purity
and activity are necessary to increase the efficiency of saponin conversion. A good
example of effective purification is to utilize the elastin-like polypeptide (ELP)
system. This purification method has the advantages of high purity, low cost and
simple operation. In this study, we optimized the purification conditions of BglPm-
ELP by the inverse transition cycle (ITC) method. In addition, we also investigated
the enzymatic characteristics of the enzyme.
