Figure 2.

A representative structure of the non-galactosylated N-glycan with α(1-3)-linked core fucose (ngf) is shown in panel a), with on the right-hand side the corresponding heat map showing the conformations accessible to the (1-6) arm in terms of the phi/psi torsion angles. A representative structure of the non-galactosylated N-glycan with β(1-2)-linked xylose (ngx) is shown in panel b), with on the right-hand side a heat map showing the conformations accessible to the (1-6) arm in terms of the phi/psi torsion angles. The N-glycans structures are shown with the (1-3) and (1-6) arms on the left and on the right, respectively. The monosaccharides colouring follows the SFNG nomenclature. The structure rendering was done with VMD (https://www.ks.uiuc.edu/Research/vmd/) and the graphical statistical analysis with RStudio (https://www.rstudio.com).
