Enhancing Accuracy in Molecular Weight Determination of Highly Heterogeneously Glycosylated Proteins by Native Tandem Mass Spectrometry
The determination of molecular weights (MWs) of heavily glycosylated proteins is seriously hampered by the physicochemical characteristics and heterogeneity of the attached carbohydrates. Glycosylation impacts protein migration during sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis (PAGE) and size-exclusion chromatography (SEC) analysis. Standard electrospray ionization (ESI)-ma...
متن کاملThe Binding Properties of Glycosylated and Non-Glycosylated Tim-3 Molecules on CD4+CD25+ T Cells
BACKGROUND T cell immunoglobulin and mucin domain containing 3 protein (Tim-3) expressed on terminally differentiated Th1 cells plays a suppressive role in Th1-mediated immune responses. Recently, it has been shown that N-glycosylation affects the binding activity of the Tim-3-Ig fusion protein to its ligand, galectin-9, but the binding properties of non-glycosylated Tim-3 on CD4(+)CD25(+) T ce...
متن کاملPolar Glycosylated and Lateral Non-Glycosylated Flagella from Aeromonas hydrophila Strain AH-1 (Serotype O11)
Polar and but not lateral flagellin proteins from Aeromonas hydrophila strain AH-1 (serotype O11) were found to be glycosylated. Top-down mass spectrometry studies of purified polar flagellins suggested the presence of a 403 Da glycan of mass. Bottom-up mass spectrometry studies showed the polar flagellin peptides to be modified with 403 Da glycans in O-linkage. The MS fragmentation pattern of ...
متن کاملCalreticulin functions in vitro as a molecular chaperone for both glycosylated and non-glycosylated proteins.
Calreticulin (CRT) is thought to be a molecular chaperone that interacts with glycoproteins exclusively through a lectin site specific for monoglucosylated oligosaccharides. However, this chaperone function has never been directly demonstrated nor is it clear how lectin-oligosaccharide interactions facilitate glycoprotein folding. Using purified components, we show that CRT suppresses the aggre...
متن کاملIdentification and characterization of allergens in spices by mass spectrometry
Background One of the major sources of hidden allergens in food is the use of spices that contain undeclared allergenic ingredients. Sesame and mustard are highly relevant in this context, as both seeds are frequently used in a variety of spices and can elicit severe allergenic reactions. Major allergens of mustard and sesame belong to the 2S-albumin family of seed storage proteins. 2S-albumins...
