ABO, Le, and secretor genes control the enzyme glycosyltransferase. Glycosyltransferases attach sugar molecules to disaccharide precursors and build oligosaccharide structures on the cell surface of red blood cells and vascular endothelium as well as in the exocrine secretion system, including the respiratory tract.
This mechanism is corroborated by the observation that individuals with non-O blood group have circulating levels of both VWF and FVIII that are approximately 25% higher than those in O blood group subjects [18]; the presence of ABH antigenic structures on circulating VWF modulates their activity through specific glycosyltransferase enzymes [20].

LpxB is the glycosyltransferase that forms the base glucosamine disaccharide of lipid A, catalyzing the formation of the glycosidic bond between the anomeric carbon of the UDP-DAG glucosamine and the 6-hydroxyl of lipid X to form lipid A disaccharide [56].
The enzymes responsible for these alterations are regulated by oncogenic growth factor signaling and represent novel therapeutic targets for cancer diagnostic and therapeutic strategies, such as the development of glycosyltransferase inhibitors, glycomimetics, and glycan/glycopeptide-based vaccines [51].
These mechanisms of resistance are also characterized by higher rates of herbicide detoxification due to increased glutathione-s-transferase, cytochrome [P.sub.450] monooxygenase or glycosyltransferase activities (Delye et al., 2013).
