glycoprotein | pancreatic enzyme has three glycosylation sites, Asn34, Asn76 and Asn88. The majority of the glycans from the normal pancreas enzyme are fucosylated complex biantennary structures. Triantennary and tetrantennary fucosylated glycans are present in the highly glycosylated enzyme fractions, together with traces of glycans with poly-N-acetyllactosamine chains and others. The main core structures of the Capan-1 enzyme are hybrid glycans with branched 3-antenna and biantennary structures containing mainly Gal-GlcNAc chains, both types of compounds substituted with up to three fucose residues and some additionally sialylated. MDAPanc-3 enzyme has sialic acids and fucose linked alpha1-3 and 1-4 to the antennae and core fucose, and galactose residues linked beta1-4 to GlcNAc | Homo sapiens |
