Antidiabetic Properties of Dietary Phenolic Compounds: Inhibition Effects on α-Amylase, Aldose Reductase, and α-Glycosidase [PDF]
Biotechnology and Applied Biochemistry, 2019 Aldose reductase (AR), alpha-amylase, and alpha-glycosidase are vital enzymes to prevent diabetic complications. Here, AR was purified from sheep kidney using elementary methods with 111.11-purification fold and with 0.85% purification yield.

Current Opinion in Chemical Biology, 2000
Insights into glycosidase mechanisms have come from X-ray crystallographic studies on complexes with substrate analogs and inhibitors, representing all the intermediate species along the reaction coordinate. Site-directed mutagenesis continues to play a significant role in understanding mechanisms, but is also proving important in generating ...

Current Opinion in Chemical Biology, 2002
The three-dimensional structure of glycosidases and of their complexes and the study of transition-state mimics reveal structural details that correlate with mechanism. Of particular interest are the transition-state conformations harnessed by individual enzymes and the substrate distortion observed in enzyme-ligand complexes.

Annual Review of Biochemistry, 1999
▪ Abstract Enzymatic hydrolysis of glycosides can occur by one of two elementary mechanisms identified by the stereochemical outcome of the reaction, inversion or retention. The key active-site residues involved are a pair of carboxylic acids in each case, and strategies for their identification and for probing the details of their roles in catalysis

Glycosidase Activities of Mycoplasmas
Zentralblatt für Bakteriologie, 1990The activities of alpha- and beta-glucosidase, beta-galactosidase and beta-N acetylglucosaminidase were assessed at acidic pH by fluorimetry using the appropriate 4-methylumbelliferyl substrate in four Mycoplasma species (M. pneumoniae, M. gallisepticum, M. hominis and M. capricolum) and in Acholeplasma laidlawii.

Nature, 1962
A NUMBER of sources of plant glycosidases are known, notably almonds and lucerne seed1. Having suitable substrates available, we have made a survey of a large number of common garden, farm and wayside plants for different glycosidase activities.

Assessment of Potential Interactions Between Phytase and Glycosidase Enzyme Supplementation on Nutrient Digestibility in Broilers [PDF]
Poultry Science, 2005 The effects of microbial 3-phytase and glycosidase enzymes, and their interactions, on energy values and nutrient digestibility in diets rich in nonstarch polysaccharides (NSP) were studied in diets based on corn, wheat, or barley.

GLYCOSIDASES IN THE CORPUS LUTEUM
Journal of Endocrinology, 1961SUMMARY 1. The corpus luteum in cattle, pigs and women is rich in α-l-fucosidase, β-d-fucosidase, β-d-galactosidase, α-d-mannosidase, β-d-glucuronidase and β-N-acetyl-d-glucosaminidase activity. In comparison, the activity of these enzymes in the follicular fluid is usually negligible.
