environment is to modulate binding interactions between proteins and glycoconjugates [6, 7]. In contrast to the large number of sulfotransferases eukaryotic systems into the domain of Prokarya. Rhizo-bia are nitrogen-fixing bacteria that enter into a symbi-Berkeley, California 94720 otic relationship with a variety of legumes. The sulfotran-sferases, NodH and NoeE, catalyze the sulfation of sec...

A helical tyrosine-sulfated epitope in CCR5 that is recognized by the human immunodeficiency virus type-1 envelope glycoprotein gp120 in its CD4-induced conformation can be mimicked structurally by a cyclic β-hairpin peptide containing two sulfated tyrosine residues at positions i and i + 2 along one β-strand.

Capillary electrophoresis (CE) was used to optimize the buffer pH, ionic strength and sulfated cyclodextrin concentrations for enantiomeric separation of piperoxan. These enantioseparation conditions were then applied to a classical gel electrophoresis system. Binding constants of the sulfated beta-cyclodextrin-piperoxan couple were approximated using CE and the effects of organic solvents on t...

nowadays, the use of innovative nano-technology in the food industry quality control has significantly increased and it is widely employed in numerous fields such as diagnosis of microbial toxin of foods using nano-biosensors, increasing food shelf-life with the help of nano-clay and nano-silver packaging, as well as changing some of the unpleasant organoleptic properties such as taste, color, ...

By combining the partition method for enrichment of sulfatides without any chromatographic procedures and the preparation method of lysosulfatides, we succeeded in analyzing these sulfated glycosphingolipids from biological materials by matrix-assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI-TOF MS) to reduce the complexity of mass fragmentation patterns within a...

Sulfated glycoproteins were purified from tryptic digests of hog stomach mucosa. The sulfated glycoprotein fractions were isolated by ethanol and cetylpyridinium chloride precipitation followed by free-flow electrophoresis. The separation of the sulfated glycoproteins was performed by elution from DEAE-Sephadex A-50 with NaCl. After gel filtration of the major fractions on Bio-Gel A-5Om, final ...

Chondroitin/dermatan sulfate (CS/DS) proteoglycans consist of unbranched sulfated polysaccharide chains of repeating GalNAc-GlcA/IdoA disaccharide units, attached to serine residues on specific proteins. The CS/DS proteoglycans are abundant in the extracellular matrix where they have essential functions in tissue development and homeostasis. In this report a phylogenetic analysis of vertebrate ...
