Purification and Characterization of a Ginsenoside Rb1-Hydrolyzing β-Glucosidase from Aspergillus niger KCCM 11239
Rb(1)-hydrolyzing β-glucosidase from Aspergillus niger KCCM 11239 was studied to develop a bioconversion process for minor ginsenosides. The specific activity of the purified enzyme was 46.5 times greater than that of the crude enzyme. The molecular weight of the native enzyme was estimated to be approximately 123 kDa. The optimal pH of the purified enzyme was pH 4.0, and the enzyme proved high...

متن کاملSecretion of the alpha-galactosidase from Cyamopsis tetragonoloba (guar) by Bacillus subtilis.
A fusion of DNA sequences encoding the SPO2 promoter, the alpha-amylase signal sequence from Bacillus amyloliquefaciens, and the mature part of the alpha-galactosidase from Cyamopsis tetragonoloba (guar) was constructed on a Bacillus subtilis multicopy vector. Bacillus cells of the protease-deficient strain DB104 harboring this vector produced and secreted the plant enzyme alpha-galactosidase u...
متن کاملPurification and characterization of a novel and unique ginsenoside Rg1-hydrolyzing β-D-glucosidase from Penicillium sclerotiorum.
In this paper, a novel and unique ginsenoside Rg(1)-hydrolyzing β-D-glucosidase from Penicillium sclerotiorum was isolated, characterized, and generally described. The β-glucosidase is an ~180 kDa glycoprotein with pI 6.5, and consists of four identical subunits of ~40 kDa. The β-glucosidase was active in a narrow pH range (4-5) and at relatively high temperature (60-70°C). The optimal activity...
متن کاملPurification, Gene Cloning, and Biochemical Characterization of a β-Glucosidase Capable of Hydrolyzing Sesaminol Triglucoside from Paenibacillus sp. KB0549
The triglucoside of sesaminol, i.e., 2,6-O-di(β-D-glucopyranosyl)-β-D- glucopyranosylsesaminol (STG), occurs abundantly in sesame seeds and sesame oil cake and serves as an inexpensive source for the industrial production of sesaminol, an anti-oxidant that displays a number of bioactivities beneficial to human health. However, STG has been shown to be highly resistant to the action of β-glucosi...
