1.10.3.3 glycoprotein 11.2% carbohydrate 439932 1.10.3.3 glycoprotein 2.4% carbohydrate 439895 1.10.3.3 glycoprotein 4 possible N-glycosylation sites 439903 1.10.3.3 glycoprotein a poorly glycosylated enzyme is produced in cell cultures treated with 0.004 mg/ml tunicamycin that is more active than the native enzyme 439937 1.10.3.3 glycoprotein Asn92 is the attachment site for one of the two N-linked sugar moieties, which has defined electron density for the N-linked N-acetylglucosamine ring. Three putative attachment sites for N-glycosidiclinked carbohydrate moieties are present in the amino acid sequence of AOase from Zucchini, i.e. Asn92-Phe93-Thr94, Asn325-Phe326-Thr327, and Asn440-Leu441 -Ser442, but only Asn92 shows density for an N-acetyl-glucosamine group 717986 1.10.3.3 glycoprotein enzyme contains 3% carbohydrates, deglycosylation studies 439910 1.10.3.3 glycoprotein enzyme may be a protein-copper carbohydrate complex 439889
