Structure and function of a β-1,2-galactosidase from Bacteroides xylanisolvens, an intestinal bacterium [PDF]

Communications Biology
Galactosides are major carbohydrates that are found in plant cell walls and various prebiotic oligosaccharides. Studying the detailed biochemical functions of β-galactosidases in degrading these carbohydrates is important.

In vitro investigations on the impact of fermented dairy constituents on fecal microbiota composition and fermentation activity [PDF]

Microbiology Spectrum
Fermented dairy constitutes a major dietary source and contains lactose as the main carbohydrate and living starter cultures, which can encounter the intestinal microbiota after ingestion.

Cold-Active β-Galactosidases: Insight into Cold Adaptation Mechanisms and Biotechnological Exploitation

Marine Drugs, 2021
β-galactosidases (EC 3.2.1.23) catalyze the hydrolysis of β-galactosidic bonds in oligosaccharides and, under certain conditions, transfer a sugar moiety from a glycosyl donor to an acceptor.

Infant-Associated Bifidobacterial β-Galactosidases and Their Ability to Synthesize Galacto-Oligosaccharides

Frontiers in Microbiology, 2021
Galacto-oligosaccharides (GOS) represent non-digestible glycans that are commercially produced by transgalactosylation of lactose, and that are widely used as functional food ingredients in prebiotic formulations, in particular in infant nutrition.

Analysis of Domain Architecture and Phylogenetics of Family 2 Glycoside Hydrolases (GH2). [PDF]

PLoS ONE, 2016
In this work we report a detailed analysis of the topology and phylogenetics of family 2 glycoside hydrolases (GH2). We distinguish five topologies or domain architectures based on the presence and distribution of protein domains defined in Pfam and ...

Galacto-Oligosaccharide (GOS) Synthesis during Enzymatic Lactose-Free Milk Production: State of the Art and Emerging Opportunities

Beverages, 2022
Much attention has recently been paid to β-Galactosidases (β-D-galactoside galactohidrolase; EC 3.2.1.23), commonly known as lactases, due to the lactose intolerance of the human population and the importance of dairy products in the human diet.

Role of glycosylation in secretion and stability of micromycetes α-galactosidase [PDF]

The Ukrainian Biochemical Journal, 2014
The effect of the glycosylation inhibitors (tunicamycin and 2-deoxy-D-glucose) on the activity, stabili­ty and production of fungal glycosidases has been studied.
