Phylogenetic relationships of LodA-like proteins. The tree was constructed using the Neighbor-Joining method built in the MEGA6 program. The distances between the proteins were computed using the p-distance method and are in the units of the number of amino acid differences per site. Numbers at branches indicate bootstrap values higher than 70% for both Neighbor-Joining and Maximum Likelihood trees. The nonclustered Gammaproteobacteria are indicated in red, Alphaproteobacteria in light blue, Betaproteobacteria in dark blue and photosynthetic microorganisms in green.
