The FGGY Carbohydrate Kinase Family: Insights into the Evolution of Functional Specificities
Figure 5
Distribution of FGGY kinase functions in a species tree extracted from a published tree of bacterial species [32].
Branches in the species tree were collapsed to show the higher taxonomic level. The colored rectangle bars (color scheme is the same as in Figure 2) on the right shows the functional distributions of each taxonomic group. The width of the bar indicates the proportion of species within a taxonomic group containing a specific function. The XylB and AraB groups are numbered according to the divisions in the protein tree to show their evolutionary patterns. The original layout was made with the Web interface of iTol [49] and was proportionally scaled and manually labeled. All rectangle bars were zoomed in proportionally so that they could be highlighted in the graph.
