http://purl.uniprot.org/citations/7737180http://www.w3.org/2000/01/rdf-schema#comment"The carbohydrate side chains of batroxobin were liberated from tryptic glycopeptides by treatment with peptide-N4-(N-acetyl-beta-glucosaminyl)asparagine amidase F, pyridylaminated and separated by two-dimensional HPLC. Neutral oligosaccharide derivatives obtained after desialylation were characterized by methylation analysis, liquid secondary-ion mass spectrometry, digestion with exoglycosidases and endoglycosidases and, in part, by acetolysis, whereas sialic acid constituents were identified by reverse-phase HPLC after conjugation with 1,2-diamino-4,5-methylene-dioxybenzene. The overall glycosylation status of the protein was studied by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The results revealed that batroxobin is heterogeneously glycosylated carrying predominantly diantennary, partially incomplete complex-type glycans in addition to hybrid-type species. Most glycans were core-fucosylated at C6 of the innermost GlcNAc. As a characteristic feature, galactose was completely replaced by GalNAc beta 4-substituents in complex-type antennae, the GlcNAc-residues of which were, in part, fucosylated at C3. Furthermore, evidence was obtained that suggested the presence of a novel type of glycoprotein-N-glycan comprising two GalNAc beta 4GlcNAc beta 4GlcNAc beta 2Man-antennae. Sialic acid residues represented a mixture of N-acetylneuraminic acid (Neu5Ac) and N-acetyl-4-O-acetylneuraminic acid (Neu4,5Ac2), which were exclusively linked to C3 of subterminal GalNAc. A precise assignment of these sialic acid derivatives to distinct oligosaccharide structures or antennae, however, was not carried out. Finally, MALDI-TOF-MS demonstrated that both potential N-glycosylation sites of batroxobin are substituted by carbohydrate chains. In conclusion, our studies revealed that this snake venom glycoprotein is characterized by a unique oligosaccharide pattern partly comprising novel structural elements."xsd:string
