Question

Oligomers (“oh-LIG-oh-mers”) named for being “high” in this molecule help “shield” gp120 from antibodies. The FimH (“fim-H”) protein of uropathogenic (“uro-pathogenic”) E. coli binds to this molecule to anchor itself to the urothelium (“uro-THEE-lee-um”). Nonamers (“NON-uh-mers”) of this molecule are targeted for glucosylation by UGGT, which marks partially folded proteins for binding by calnexin. The synthesis of “hybrid” and “complex” antigens begins with removing units of this molecule from N-X-T sites in the trans-Golgi. Recognition of this molecule and glucose by C-type lectins triggers (10[1])one of the three (-5[1])canonical (10[1])complement (10[2])cascades. (-5[1])In enzyme replacement therapy, this molecule is added to recombinant iduronidase with N-glycosylation. (-5[1])Inclusion cells are formed by an inability to phosphorylate this anomer (10[1])(“ANN-oh-mer”) of glucose. (10[2])For 10 points, name this sugar (10[1])whose (10[1])“6-phosphate” (10[1])derivative (10[3]-5[1])directs proteins (10[2])to the lysosome. ■END■ (10[5]0[5])

ANSWER: mannose [or D-mannopyranose; accept mannose-6-phosphate; accept oligomannose; accept mannans; accept high-mannose glycans; prompt on sugars, carbohydrates, monosaccharides, or aldohexoses until “sugar” is read]
