Synthesis, glycosidase inhibitory activity and computational studies of dideoxymethylnojirimycin and its derivatives

Results in Chemistry, 2023
We report here the synthesis and biological evaluation of dideoxynojirimycin and its analogs and their functional effect on glucosidase enzyme inhibition against α-glucosidase(yeast), α-galactosidase and β-galactosidase (kluyveromyces lactis).

High-yield production and biochemical characterization of α-galactosidase produced from locally isolated Penicillium sp.

Bulletin of the National Research Centre, 2020
Background α-Galactosidase is widely used in various biotechnological applications such as food processing, beet sugar, the pulp and paper industries, synthesis of oligosaccharides by trans-galactosylation, hydraulic fracturing of oil and gas wells, and ...

Effect of tunicamycin on α-galactosidase secretion byAspergillus nidulansand the importance ofN-glycosylation [PDF]

FEMS Microbiology Letters, 1994
Aspergillus nidulans released α-galactosidase into the culture medium during the exponential growth on either lactose or galactose as the only carbon source. This enzyme is a glycoprotein. Its treatment with endoglycosidases produces a reduction in its molecular mass but the resulting enzyme conserved some of their carbohydrate components in addition ...

Thermostable α-galactosidase fromThermotoga neapolitana: cloning, sequencing and expression [PDF]

FEMS Microbiology Letters, 1998
A gene encoding a thermostable alpha-galactosidase from the hyperthermophile Thermotoga neapolitana was cloned and sequenced. Sequence analysis showed that the 552-amino acid protein is similar to Escherichia coli Raf type alpha-galactosidase and belongs to Family 36 of the glycosyl hydrolases. Recombinant alpha-galactosidase expressed in E. coli has a

Immobilization of the Antarctic sp. LX-1 α-Galactosidase on Eudragit L-100 for the Production of a Functional Feed Additive [PDF]

Asian-Australasian Journal of Animal Sciences, 2013
Partially purified α-galactosidase from Bacillus sp. LX-1 was non-covalently immobilized on a reversibly soluble-insoluble polymer, Eudragit L-100, and an immobilization efficiency of 0.93 was obtained.

Recovery and Screening of α-Galacotosidase Producing Lactic Acid Bacteria from Fermented Dairy Products

Journal of Basic and Applied Research in Biomedicine, 2022
Lactic acid bacteria (LAB) present in fermented foods has long been consumed by humans without any obvious adverse effects. Therefore, they are potent candidates as vehicles for the delivery of digestive enzymes.

Yersinia pestis lacZexpresses a β-galactosidase with low enzymatic activity [PDF]

FEMS Microbiology Letters, 2006
Although very little, if any, beta-galactosidase activity is detected in Yersinia pestis by a standard Miller assay, we found that Y. pestis KIM6+ cells formed blue colonies on plates containing 5-bromo-4-chloro-3-indolyl-beta-D-galactoside (X-gal). Searches of the Y.

Thermostable α-galactosidase fromBacillus stearothermophilusNUB3621: cloning, sequencing and characterization [PDF]

FEMS Microbiology Letters, 1999
An alpha-galactosidase gene from the thermophilic bacterium Bacillus stearothermophilus NUB3621 was cloned, sequenced, expressed in Escherichia coli and the recombinant protein was purified. The Bacillus enzyme, designated AgaN, is similar to alpha-galactosidases of family 36 in the classification of glycosyl hydrolases.

A food-grade vector for Streptococcus thermophilus based on the α-complementation of β-galactosidase

Journal of Dairy Science, 2022
: Streptococcus thermophilus is a common yogurt starter that consumes lactose as its primary carbon source. The enzyme β-galactosidase is essential for the lactose metabolism and the growth of this species.
