Comparative analysis of bisected and non-bisected biantennary glycans using PDB data.
(A) Plot of dihedral angles of Manα1–3Man linkage. The ϕα1–3 and φα1–3 are plotted in horizontal and vertical axes, respectively. The bisected and non-bisected biantennary glycans are plotted as blue and red circles, respectively. (B) Plot of dihedral angles of Manα1–6Man linkage. For clarity, the ϕα1–6, φα1–6 and ωα1–6 are plotted from 0° to 360° instead of −180° to 180°. Conformations of non-bisected and bisected glycans are plotted in red and blue, respectively. Five proposed conformations, extend-a (Ex-a), extend-b (Ex-b), back-fold (BF), half back-fold (HBF) and tight back-fold (TBF) are indicated with asterisks. (C) Histograms of three dihedral angles of Manα1–6Man linkage. The bisected and non-bisected biantennary glycans are shown in right and left panels, respectively.
