Minimum Evolution Phylogenetic tree reconstructed on the basis of ScyD and ScyE amino acid sequences. Phylogenetic trees were created with bootstrap values from 500 replicates. N. punctiforme NAD(P)H-quinone oxidoreductase subunit H (NdhH) was used as the outgroup sequence. This topology is supported by both Neighbor-Joining and Maximum-Likelihood methods (see Supplementary Figure S6). Blue box highlights the ScyE cluster, while the yellow box the ScyD. The GenBank accession number for each protein is given between brackets.
