Diglycoside-Specific Glycosidases
2003Publisher Summary The chapter focuses on β -primeverosidase, which is is one of the disaccharide-specific glycosidases, or “diglycosidases.” A β -primeverosidase responsible for the formation of aroma from the glycosidic aroma precursors was purified from the crude enzyme extract prepared from fresh juvenile tea leaves (Camellia sinensis).

Glycosidases in cancer and invasion
CANCER AND METASTASIS REVIEW, 1985Glycosidases have been demonstrated to be elevated in the interstitial fluid of tumors, sera of animals and patients with tumors, and in some tumor tissue as compared to normal adjacent tissue. Elevations of serum beta-N-acetylglucosaminidase and beta-glucuronidase most commonly have been found to occur and these enzymes have been shown to be secreted ...

Engineering of glycosidases and glycosyltransferases
Current Opinion in Chemical Biology, 2006In recent years, substantial advances have been made in the engineering of glycosidases and glycosyltransferases for the synthesis and degradation of glycan structures. Key developments include improvement of the thermostability of xylanase through comprehensive saturation mutagenesis, creation of the first glycosynthase derived from an inverting ...

Sugarcane glycosidases A general view of the glycosidases from stalk
Plant Science Letters, 1977Abstract A general study of the glycosidases from sugarcane stalks has been undertaken. Eight glycosidase activities were found, an α-glucosidase which was active on maltose but not on turanose, two α-galactosidases with different pH optima, a polygalacturonase and minor amounts of a β-galactosidase and methylpolygalacturonase activity.

Glycosidases ofTrichinella spiralis
Molecular and Biochemical Parasitology, 1985The exoglycosidases beta-N-acetyl-D-glucosaminidase, beta-N-acetyl-D-galactosaminidase, alpha-1-fucosidase, alpha-D-glucosidase and alpha-D-mannosidase, and a non-specific acid phosphohydrolase are present at high levels in extracts of adult and muscle-stage (L1) Trichinella spiralis and at lower (5-30-fold) levels in extracts of the newborn larvae ...

The glycosidases of Cellulomonas
Biotechnology Letters, 1981A Cellulomonas strain, with potential for saccharification of sugar cane bagasse, has been found to possess a range of glycosidase activities which could be necessary for effective hydrolysis of the hemicellulose fraction of the bagasse.

AbstractGlycosidases isolated from the mill fractions made from soft and hard wheat grists were studied. α‐Arabinosidase, α‐galactosidase, β‐galactosidase, β‐glucosidase, β‐glucuronidase, β‐mannosidase and β‐xylosidase activities in wheat flour, germ and bran were determined under standard dough conditions. There were no significant differences between

Conditions required to stabilize ß-galactosidase activity in apple extracts were found. ß-Galactosidase was most stable at neutral pH and in the presence of certain additives, in particular PVP and CETAB, which were used in the purification. Most of the glycosidase activities present in the apple were effectively extracted with 50 mmol/L phosphate ...
