an autosomal recessive defect in udp-n-acetylglucosamine : lysosomal enzyme n-acetylglucosamine-1-phosphotransferase ) was studied to determine whether or not the defect in the phosphorylation of lysosomal enzyme mannose residues resulted in a failure of target-cell lysis , as would be predicted from recent studies showing nk inhibition by phosphorylated sugars , especially mannose-6-phosphate .
