Fig. 5: Glycan similarity of sugar repeat units polymerized by BP-Pols.

All “seed” BP-Pols where the corresponding transferred oligosaccharide was known were included in the heatmap. A phylogenetic tree is shown for the polymerases in each CAZy family on the left. The glycan similarity scores are shown in a color scale of light blue (score value of 2 corresponding to identical matches at both −1 and +1 sites) to dark blue (score value of 5 corresponding to identical matches for at least three additional sequential positions). Horizontal lines separate the families. The darker colors close to the diagonal and within the families indicate specific substrate similarities in each family.
