A robust enzymatic reporter system for the extremely thermophilic anaerobic bacterium Anaerocellum bescii [PDF]

Frontiers in Microbiology
Thermophilic anaerobic organisms, particularly species that can naturally degrade lignocellulosic biomass, show great promise for next generation bioprocessing.

Identification and characterization of a novel β-galactosidase active at low temperatures from the Antarctic fungus Tetracladium sp., expressed in Saccharomyces cerevisiae [PDF]

Microbial Cell Factories
Background β-Galactosidases are widely used in the dairy industry to produce lactose-free milk and prebiotics such as galacto-oligosaccharides and lactulose.

Biochemical characterization of three Aspergillus niger β-galactosidases

Electronic Journal of Biotechnology, 2017
Background: β-Galactosidases catalyze both hydrolytic and transgalactosylation reactions and therefore have many applications in food, medical, and biotechnological fields.

Sequence‐Based and Functional Analysis for the Discovery of N‐Glycan Degrading Glycosidases From the Microbial Metagenome of the Infant Gut [PDF]

MicrobiologyOpen
The role of bacterial glycosyl hydrolases (GHs) in degrading free human milk oligosaccharides is well documented. However, their activity on glycoconjugates is less well known.

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.

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.

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 ...

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.

Properties of cerebroside galactosidase [PDF]

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1968
SUMMARY Rat brain cerebrosidase was shown by centrifugal fractionation to be a lysosomal enzyme. The pH optimum was found to be 4.5. Taurocholate greatly stimulated its action. The addition of palmitic acid had little effect on the enzyme activity, but ceramide, sphingosine, and ceramide lactoside inhibited.

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.
