Figure 5 Stereoscopic diagrams of the oligosaccharide structure in [284][beta] -MMC, prepared using the molecular-graphics program TURBO-FRODO. (a) The (2F[o] - F[c]) electron density of the oligosaccharide of molecule A, contoured at 0.8 [285][sigma] . Asn51 is also shown. (b) The (2F[o] - F[c]) electron density of the oligosaccharide of molecule B, contoured at 0.8 [286][sigma] . Asn51 is also shown. (c) The superimposed oligosaccharides of molecule A (in blue) and molecule B (in red). (d) Interactions of the oligosaccharide (in blue) of molecule A with the protein. Asn51 of molecule A is shown in yellow; Glu110, Asn188-Glu189 and the C-terminus (Asn249) of molecule #A are shown in red. The N-glycosidic bond is shown as a solid line and the hydrogen bonds are shown as dashed lines. (e) Interactions of the oligosaccharide (in blue) of molecule B with the protein. Asn51 and Asn3 of molecule B are shown in yellow; Gln189 and Asn209 of molecule #B are shown in red. The N-glycosidic bond is shown as a solid line and the hydrogen bonds are shown as dashed lines.
