glycoprotein
glycoprotein
-
enzyme form F4 and F5 contain fucose, N-acetylglucosamine, xylose and mannose in the ratio of 1.0:2.0:1.0:2.0, but only 50% of the proteins seem to be glycosylated, enzyme form F9 is unglycosylated
glycoprotein
-
carbohydrate content: 4.3% (enzyme form SBB1), 3.6% (enzyme form SBB2), 3.5% (enzyme form SBB3), 8.2% (enzyme form SBA), enzyme form SBB4 and SBB5 contain no carbohydrate
glycoprotein
-
carbohydrate composition: molar ratio of mannose:xylose:fucose is 2.43:1.0:1.01 (enzyme form SB1), 2.55:1.17:0.92 (enzyme form SB2)
glycoprotein
-
neutral sugar content: 4.89% (enzyme form SB1), 5.24% (enzyme form SB2)
glycoprotein
-
both isozymes are highly glycosylated, isozyme SBA/a is about 2fold more glycosylated than isozyme SBA/b, glycoslyation composition
glycoprotein
-
glycosylation stabilizes the enzyme, enzyme contains a single hetero-oligosaccharide unit per molecule, deglycosylated enzyme shows decreased activity
glycoprotein
-
contains a single oligosaccharide chain attached to the polypeptide
