Phylogenetic analysis of GalU and GalF. Phylogenetic relationship of prokaryotic UDP-Glc PPases. The rooted trees were built as described in Experimental Procedures, and reference numbers in bold are listed on Supplementary Table S2. The scale on the bottom left represents the number of substitutions per site. Green branches belong to GalF proteins, whereas pink branches are GalU proteins from enterobacteria. Between brackets, it is indicated the residues conserved in each group in the positions corresponding to T20 (first bracket) and R21 (second bracket) in E. coli GalU. Arrows indicate the sequences of E. coli proteins.
