Biocatalytic approaches using lactulose: end product compared with substrate [PDF]

, 2016
Lactulose is a lactose-based carbohydrate with well-known prebiotic effect and recognized medical applications. Currently, the commercially available lactulose is chemically synthesized. Nevertheless, the process leads to low yields and high levels of by-

Pre‐Encoded IFN‐I Sensitivity Exacerbates Memory T Cell Senescence in Solid Tumors

Advanced Science, EarlyView.
Type I interferon (IFN‐I) signaling promotes p21‐dependent cell cycle arrest in senescent tumor‐specific memory T cells, resulting in poor proliferative responses and solid tumor regression during cancer vaccination. Conversely, IFNα/β receptor blockade reinvigorates T cell proliferation to regress solid tumors and is more effective with increasing ...

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.

Detection of Protein–Protein Interactions in Escherichia coli With Single Molecule Sensitivity

Advanced Science, EarlyView.
This article describes a regulatory circuit in Escherichia coli able to detect protein–protein interactions with exquisite sensitivity. The interaction between two hybrid proteins fused to Bordetella pertussis adenylate cyclase and its activator calmodulin triggers a potent cyclic AMP signaling cascade.

Research Progess in the Evolution and Functions of Plant α-galactosidases

Guangdong nongye kexue, 2022
α-galactosidase (α-gal, EC 3.2.1.22) is a kind of exoglycosidase that can specifically catalyze the hydrolysis ofα-galactoside bonds. It has the ability to hydrolyze theα-1, 6-galactoside bonds involved in galacto-oligosaccharides such as melibiose ...

Galacto-Oligosaccharides : production, properties, applications, and significance as prebiotics [PDF]

, 2010
Galacto-oligosaccharides (GOS) have now been definitely established as prebiotic ingredients after in vitro and animal and human in vivo studies. Currently, GOS are produced by glycoside hydrolases (GH) using lactose as substrate.
