The composition, structure, and thermal stability of carrageenans from unattached Coccotylus truncatus (the Baltic Sea, Estonia) were investigated. The complex polysaccharide was characterized by (13)C NMR and FTIR spectroscopy, ICP-OES and gel permeation chromatography methods. The main components of C.

The carbohydrate-protein linkage region of a chondroitin 4-sulfate chain attached to urinary trypsin inhibitor (UTI) was isolated from human urine and characterized structurally. The chondroitin 4-sulfate chain was released from UTI by beta-elimination using alkaline NaBH4 then digested with chondroitinase

iota-Carrageenases are polysaccharide hydrolases that cleave the beta-1,4 linkages between the d-galactose-4-sulfate and 3, 6-anhydro-d-galactose-2-sulfate residues in the red algal galactans known as iota-carrageenans. We report here on the purification of iota-carrageenase activity from the marine bacterium Zobellia galactanovorans and

The first step in the pathogenesis of enterotoxigenic Escherichia coli (ETEC) infections is adhesion of the bacterium to the small intestinal epithelium. Adhesion of ETEC is mediated by a number of antigenically distinct colonization factors, and among these, one of

Virulence, 11(1), 381-390 (2020-04-05)
The ability to adhere via colonization factors to specific receptors located on the intestinal mucosa is a key virulence factor in enterotoxigenic Escherichia coli (ETEC) pathogenesis. Here, the potential glycosphingolipid receptors of the novel human ETEC colonization factor CS30 were
