FIGURE

 

Fig.1 Adiabatic φ/ψ energy maps for the glycosidic linkages for the different disaccharide sub-structures of the repeating unit (plus one downstream residue) of B. cepacia. Contour levels are shown at every kcal/mol with blue for low-energy regions and red for high energy levels (a) The α-D-GlcpA-(1→3)-α-D-Manp linkage. (b) α-D-Galp-(1→2)-α-D-GlcpA. (c) β-D-GlcpA-(1→3)-α-D-GlcpA. (d) &alpha-D-Rhap-(1→4)-α-D-GlcpA. (e) β-D-Galp-(1→2)-α-D-Rhap. (f) β-D-GlcpA-(1→6)-α-D-Manp. f1 for φ/ψ, f2 for ω/ψ and f3 for φ/ω. (g) α-D-Manp-(1→3)-β-D-Glcp. The white dots show the torsion angle values of the global minimum for the repeat unit according to GLYGAL, the balck dots show the position of the major secondary minima of the repeating unit.
