Functional metagenomics reveals novel β-galactosidases not predictable from gene sequences. [PDF]

PLoS ONE, 2017
The techniques of metagenomics have allowed researchers to access the genomic potential of uncultivated microbes, but there remain significant barriers to determination of gene function based on DNA sequence alone.

O estresse salino retarda o desenvolvimento morfofisiológico e a ativação de galactosidases de parede celular em caules de Vigna unguiculata Salt stress delays morphophysiological development and activation of cell wall galactosidases in Vigna unguiculata stems

Acta Botânica Brasílica, 2011
Com o objetivo de examinar o envolvimento das α- e β-galactosidases na expansão celular de caules de plântulas de feijão-de-corda submetidas a estresse salino durante o estabelecimento da plântula, e de analisar os efeitos do estresse salino no

Selection of lactic acid bacteria strain for simultaneous production of α- and β-galactosidases

Zaštita Materijala, 2016
Galactosidases are group of enzymes gaining increasing attention in recent times due to the fact they catalyse hydrolysis of galatose-containing oligosaccharide, which reduce digestibility of various food and feed products.

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.

The C-terminal lectin-like domain modulates the substrate specificity and transglycosylation activity of rice β-galactosidase1 (OsBGal1) [PDF]

PeerJ
Background β-galactosidases (EC 3.2.1.23) are glycosidases that release nonreducing terminal β-d-galactosyl residues from saccharides or glycosides.

Kinetic characterization of galacto‐oligosaccharide (GOS) synthesis by three commercially important β‐galactosidases

Biotechnology Progress, 2014
Many b-galactosidases show large differences in galacto-oligosaccharide (GOS) production and lactose hydrolysis. In this study, a kinetic model is developed in which the effect of lactose, glucose, galactose, and oligosaccharides on the oNPG converting ...

Immobilization of β-Galactosidases on the Lactobacillus Cell Surface Using the Peptidoglycan-Binding Motif LysM

Catalysts, 2019
Lysin motif (LysM) domains are found in many bacterial peptidoglycan hydrolases. They can bind non-covalently to peptidoglycan and have been employed to display heterologous proteins on the bacterial cell surface.

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.

Thermostable β-galactosidases for the synthesis of human milk oligosaccharides. [PDF]

New Biotechnology, 2016
Human milk oligosaccharides (HMOs) designate a unique family of bioactive lactose-based molecules present in human breast milk. Using lactose as a cheap donor, some β-galactosidases (EC 3.2.1.23) can catalyze transgalactosylation to form the human milk ...
