A Specific Near-Infrared Probe for Ultrafast Imaging of Lysosomal β-galactosidase in Ovarian Cancer Cells.

Analytical Chemistry, 2020
Reactivity based fluorescent probes have been widely investigated as a powerful and noninvasive tool for disease diagnosis in recent years. β-galactosidase (β-gal), one of the typical lysosomal glycosidases, is reported to be a vital biomarker ...

Immobilization of β-galactosidase on tannic acid stabilized silver nanoparticles: A safer way towards its industrial application.

Spectrochimica Acta Part A - Molecular and Biomolecular Spectroscopy, 2020
In this study, β-galactosidase has been immobilized on tannic acid stabilized silver nanoparticles (AgNPs). Tannic acid is a phytochemical and it is advantageous to use it as a linker molecule for immobilization because of its antidiarrheal and ...

β‐Galactosidase: Insights into source variability, genetic engineering, immobilisation and diverse applications in food, industry and medicine

International Journal of Dairy Technology
β‐Galactosidases are crucial enzymes that hydrolyse oligosaccharides and polysaccharides with terminal β‐1,4‐glycosidic bonds. Though the traditional application of β‐Galactosidases has been to catalyse the breakdown of lactose in dairy products, its ...

Recent advances of molecular optical probes for imaging of β-galactosidase.

Bioconjugate chemistry, 2019
β-galactosidase (β-Gal), as a lysosomal hydrolytic enzyme, plays an important physiological role in catalyzing the hydrolysis of glycosidic bonds which convert lactose into galactose. Moreover, upregulation of β-Gal is often correlated with occurrence of

GM1 gangliosidosis and Morquio B disease: expression analysis of missense mutations affecting the catalytic site of acid β-galactosidase

Human Mutation, 2009
Alterations in GLB1, the gene coding for acid beta-D-galactosidase (beta-Gal), can result in GM1 gangliosidosis (GM1), a neurodegenerative disorder, or in Morquio B disease (MBD), a phenotype with dysostosis multiplex and normal central nervous system (CNS) function.

Production of galacto-oligosaccharides from whey permeate using β-galactosidase immobilized on functionalized glass beads.

Food Chemistry, 2018
The conversion of whey permeates to galacto-oligosaccharides (GOS) was studied by the enzymatic action of β-galactosidase from Aspergillus oryzae in a continuous flow packed-bed reactor.

Effect of tannic acid on the structure and activity of Kluyveromyces lactis β-galactosidase.

Food Chemistry, 2019
Tannins are compounds with antinutrient properties that hinder food digestibility, prejudicing human and animal nutrition. This work aimed to evaluate the negative effects of tannic acid on Kluyveromyces lactis β-galactosidase catalytic activity and ...
