The Characterization of the Fucose Sensing Kinase (FUSK) and the Fucose Sensing Response Regulator (FUSR) and Their Role in Virulence Regulation in Enterohemorrhagic Escherichia Coli O157:H7
… Biochemical studies revealed that FusK senses fucose. Fucose is an important carbon source for commensal and pathogenic bacteria during intestinal colonization. Transcriptional analyses shows that FusKR signal transduction system regulates fucose utilization indirectly, through regulation of …

Studies on fucosylation in Trypanosoma brucei
The biosynthesis of GDP-Fucose, the activated donor for fucose, has been recently shown to be essential in the parasite Trypanosoma brucei. Fucose is a common sugar modification on eukaryotic glycan structures, but it has not been well described in trypanosomatids. To elucidate the role of fucose …

Congenital Disorder of Glycosylation (CDG)-IIc: Eine retrovirale Expressionsklonierung identifiziert das CDG-IIc Syndrom (Leukozyten Adhäsionsdefekt II) als eine GDP-Fukose Transporter Defizienz
… konnte auf einen verminderten Import von GDP-Fucose in den Golgi zurückgeführt werden. Da das Gen für den GDP-Fucose Transporter noch in keiner Spezies bekannt war und zudem nicht ausgeschlossen werden konnte, dass die Transportdefizienz einen Defekt eines Transport-assoziierten Kofaktors …

GLYCOMIMETIC LIGANDS TARGETING BACTERIAL LECTINS: RATIONAL DESIGN, SYNTHESIS AND BIOPHYSICAL EVALUATION
… C-terminal dimeric domain, and a fucose-specific N-terminal trimeric domain. In previous work, a collection of bifunctional glycomimetics specifically targeting the N-terminal domain of BC2L-C (referred to as BC2LCNt) was discovered using a combination of fragment- and …

Transformation of biomass carbohydrates by transition metal catalysts
… system was used to follow the incorporation of fucose into the plant cell wall. Fucose is limited in its use by plants only becoming incorporated into branched xylan chains that help to link cellulose and hemicellulose together. The synthesis of xylan in the plant Golgi also utilizes …

Metabolomic analysis of the interleukin-10-deficient mouse model of Crohn's disease
… and wildtype C57BL/6 mice. Xanthurenic acid and fucose were identified as the main urinary metabolites associated with the early stage of intestinal inflammation. Their levels were increased in IL10-/- mice relative to wildtype. Xanthurenic acid levels were attributed to increased tryptophan …

Lipid antigens and immunoregulatory iNKT cells in the prevention and treatment of type 1 diabetes and related autoimmune diseases
… galactose sugar head for glucose (α-GlcCer) or L-fucose (α-L-FucCer) also elicited differences in the immunological profile of α-GalCer analogues, with lymphocytic proliferation being greatest in the galactose analogue, followed by L-fucose, followed by a glucose analogue. These differences in …

The role of mucin in establishment of Escherichia coli in porcine small intestine
… weight) 37.2% protein, 58.7% carbohydrate (4.6% fucose, 9.4% mannose, 10.7% sialic acid, 13.5% galactose, and 20.5% hexosamine), and 3.7% ester sulfate. Fractionation of mucin on Sepharose CL-4B yielded one peak which eluted at the void volume. However, sodium dodecyl sulfate gel electrophoretic …
