Fig. 1.

A) Schematic principle of the Umbrella Visualization: The glycan here is shown in sticks representation and colored by residue type. The Umbrella Representation considers the glycan acting as an umbrella over the protein surface. B) Implementation of the Umbrella Visualization process: The glycan is represented in sticks. The core of the Glycan, shown in green, is aligned along the z axis thanks to vectors describing the core (red arrows). The center of mass (red dots) of the last saccharide residue on the branches is projected on the xy plane. The final result is a density plot reflecting the relative flexibility of the glycan during a MD trajectory. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
