31. It is a homotetramer with 6 bilayer spanning domains and N-glycosylation sites. 32. Glycosylation of HA does not correlate with either the antigenicity or the selection pressure.33. These enzymes catalyse sialyltransfer reactions during glycosylation , and are type II membrane proteins. 34. Cytoplasmic FLT3 undergoes glycosylation , which promotes localization of the receptor to the membrane. 35. In addition, O-linked or sialylated glycosylation were not present in QSulf1. 36. There are two likely sites of glycosylation on the protein : N38 and N450. 37. Mutations in OA1 have been linked to defective glycosylation and thus improper intracellular transportation. 38. To better understand this, the mechanism of a glycosylation reaction must be considered. 39. They are modified by N-linked glycosylation . 40. The hydroxyl side-chain can undergo " O "-linked glycosylation .
