Figure 4. The role of GlcNAc6 in stabilisation of
carbohydrate-protein interactions. The structure of the
oligosaccharide moiety (chain A) of Fc-glycoform (G2F)[2] in
space group C222[1] (green) and P2[1]2[1]2[1] (blue) are shown.
In contrast to Man5 and Gal7, GlcAc6 maintains a contact to the
Cg2 domain in both structures. For GlcNAc6 of the structure in
space group C222[1] the 2F[o] -F[c] electron density map is
shown contoured at 0.8s.
