Figure 4From: Evolution and diversity of periplasmic proteins involved in copper homeostasis in gamma proteobacteriaTwo-dimensional optimization of the phylogenetic profile of periplasmic copper homeostasis proteins. Clustering optimization was rearranged for taxonomic categories preserving the previously optimized arrangement of protein presence. Eight proteins repertoires were identified (marked with dots). Shade scale represents the fractional abundance of a seed protein within a genus.Back to article page
