Lactobacillus fermentumCRL 722 is able to deliver active α-galactosidase activity in the small intestine of rats [PDF]

FEMS Microbiology Letters, 2005
alpha-galactooligosaccharides (alpha-GOS) found in legumes such as soybeans can cause gastrointestinal disorders since mammals lack alpha-galactosidase (alpha-Gal) in the small intestine which is necessary for their hydrolysis. Lactobacillus fermentum CRL 722 is a lactic acid bacterium (LAB) capable of degrading alpha-GOS due to its elevated alpha-Gal ...

Prebiotic properties of Bacillus coagulans MA-13: production of galactoside hydrolyzing enzymes and characterization of the transglycosylation properties of a GH42 β-galactosidase

Microbial Cell Factories, 2021
Background The spore-forming lactic acid bacterium Bacillus coagulans MA-13 has been isolated from canned beans manufacturing and successfully employed for the sustainable production of lactic acid from lignocellulosic biomass. Among lactic acid bacteria,

Insertion of a 27 amino acid viral peptide in different zones ofEscherichia coliβ-galactosidase: Effects on the enzyme activity [PDF]

FEMS Microbiology Letters, 1994
Seven internal, putatively exposed regions of Escherichia coli beta-galactosidase have been explored regarding their tolerance to insertions of large foreign peptides. Small sequence modifications, including amino acid substitutions and small deletions, were introduced into the lacZ gene to generate unique BamHI restriction sites. By using these mutant

Optimised N-acetyl-d-lactosamine synthesis using Thermus thermophilus β-galactosidase in bio-solvents

Tetrahedron, 2013
Synthesis of N-acetyl-D-lactosamine (Gal-β[1→4]GlcNAc, LacNAc) catalyzed by β-galactosidase from Thermus thermophilus (TTP0042) is affected by side reactions that give as result very low yields (about 20%) of LAcNAc when the reaction is performed in buffer.

Ability of Lactobacillus fermentum to overcome host α-galactosidase deficiency, as evidenced by reduction of hydrogen excretion in rats consuming soya α-galacto-oligosaccharides

BMC Microbiology, 2008
Background Soya and its derivatives represent nutritionally high quality food products whose major drawback is their high content of α-galacto-oligosaccharides.

TNF receptor–related factor 3 inactivation promotes the development of intrahepatic cholangiocarcinoma through NF‐κB‐inducing kinase–mediated hepatocyte transdifferentiation

Hepatology, EarlyView., 2022
Abstract Background and Aims Intrahepatic cholangiocarcinoma (ICC) is a deadly but poorly understood disease, and its treatment options are very limited. The aim of this study was to identify the molecular drivers of ICC and search for therapeutic targets.

EXTRACTION AND CHARACTERIZATION OF Î’-GALACTOSIDASE ENZYME FROM ZIZIPHUS SPINA-CHRISTI FOR FOOD APPLICATIONS

International Journal of Advanced Research
Galactosidaseis an industrially important enzymewitha number of applications in dairy, fermentation, and food industries. The study was carried out to extract and characterize the galactosidase enzymefromZiziphusspina-christi,a therapeutic herb. The enzyme was studied for pH, temperature sensitivity, and heavy metal effects on enzyme activity.

The role of lipid metabolism in neuronal senescence

FEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

Aging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.
