Endo-β-galactosidase was used in fractional protein isolation. It was used for deglycosylation in glycoproteomics of the endothelial secretome of human endothelial cells.
생화학적/생리학적 작용
Internal β(1-4) galactose linkages in unbranched, repeating poly-Nacetyllactosamine [GlcNAc β(1-3)Gal β (1-4)] structures are the preferred substrate.
Sulfated structures such as keratan sulfate are also cleaved. Branching and/or fucosylation of the substrate may reduce or completely inhibit cleavage. Sulfation of C-6 on galactose will block cleavage. Oligosaccharides of the neolacto-group are cleaved at greatly reduced rates depending on the deviation from the preferred substrate. For example, Gal β(1-3)GlcNAc β(1-3) Gal β(1-4)Glc is cleaved at 5X10-5 the rate of keratan sulfate
β-galactosidase cleaves lactose into its monosaccharide components, glucose and galactose. It also catalyses the transglycosylation of glucose into allolactose, the inducer of β-galactosidase, in a feedback loop.

Previous proteomics studies have partially unraveled the complexity of endothelial protein secretion but have not investigated glycosylation, a key modification of secreted and membrane proteins for cell communication. In this study, human umbilical vein endothelial cells were kept in serum-free

We hypothesized that cleavage of the extracellular matrix (ECM) proteoglycans versican and aggrecan by ADAMTS (a disintegrin and metalloprotease with thrombospondin motifs) proteases, which contributes to stress-induced ECM-reorganization in atherogenesis and osteoarthritis, also play a role in heart failure development.

ADAMTS (A Disintegrin-like and Metalloproteinase domain with Thrombospondin type 1 Motif)-1, -4 and -5 share the abilities to cleave large aggregating proteoglycans including versican and aggrecan. These activities are highly relevant to cardiovascular disease and osteoarthritis and during development. Here

In the present study, we sought to quantify and contrast the secretome and biomechanical properties of the non-chondrodystrophic (NCD) and chondrodystrophic (CD) canine intervertebral disc (IVD) nucleus pulposus (NP). We used iTRAQ proteomic methods to quantify the secretome of both

ADAMTS-5 is a major protease involved in the turnover of proteoglycans such as aggrecan and versican. Dysregulated aggrecanase activity of ADAMTS-5 has been directly linked to the etiology of osteoarthritis (OA). For this reason, ADAMTS-5 is a pharmaceutical target for
