Senescence-associated beta-galactosidase is lysosomal beta-galactosidase

Aging Cell, 2006
Replicative senescence limits the proliferation of somatic cells passaged in culture and may reflect cellular aging in vivo. The most widely used biomarker for senescent and aging cells is senescence-associated beta-galactosidase (SA-beta-gal), which is defined as beta-galactosidase activity detectable at pH 6.0 in senescent cells, but the origin of SA-

Knockout mutants of Arabidopsis thaliana β-galactosidase. Modifications in the cell wall saccharides and enzymatic activities

Biologia Plantarum, 2018
This work studied the six β-galactosidases (BGALs) of the subfamily a1 of Arabidopsis, that have been proposed to play important roles in the cell wall remodelling during plant development, although their precise functions are still unknown.

Cloning, Expression, Purification, and Characterization of β-Galactosidase from Bifidobacterium longum and Bifidobacterium pseudocatenulatum

Molecules, 2022
Expression and purification of β-galactosidases derived from Bifidobacterium provide a new resource for efficient lactose hydrolysis and lactose intolerance alleviation. Here, we cloned and expressed two β-galactosidases derived from Bifidobacterium. The

Sensory Assessment of Bi-Enzymatic-Treated Glucose-Galactose Syrup

Fermentation, 2023
There are a variety of ways to make glucose-galactose syrup (GGS) and other products of lactose hydrolysis; therefore, research is still ongoing and will undoubtedly result in improved methods and lower costs.

Whole yogurt sweetened with glucose-galactose syrup obtained by nanofiltration: Effect on galactooligosaccharides concentration, physicochemical and sensory properties

Applied Food Research, 2023
Glucose-galactose syrup is a sweetener obtained from whey. It is scarcely industrial produced due to its low level of sweetness and lower economic competitiveness compared to other traditional sugars.
