Coevolution of aah: A dps-Like Gene with the Host Bacterium Revealed by Comparative Genomic Analysis
Figure 1
Functional domain, taxonomy, and sequence similarity of Dps-like proteins. (a) Diagram display of the functional domains of Dps-like proteins. Domains are colored as described on the left. The open blank bar depicts the protein including ferroxidase center. (b) Cladogram of some Dps-like proteins with branch lengths in accordance with their relative evolutionary distance. The unit is shown on the bottom. Another set of independently calculated distance values was given in parentheses. The bootstrap values (%) of 1000 repeats were labelled on the knots. Protein names were followed by the host species. Putative proteins were labelled with the gene tag in corresponding genome projects. The ferritin from E. coli was chosen as out-group. The classification of the corresponding hosts was shown on right. Those proteins whose sequence similarities and host phylogeny do not match were marked by arrows. The protein domains were shown as squares with the same color in (a). The protein IDs were listed in the Supplementary Material available online.
