Phylogenetic dendrogram based on full-length protein sequences of SoxB illustrating the positions of members of the OM60/NOR5 clade (in bold). The SoxB sequence of Thermus thermophilus HB27 (Q72IT0) was used as outgroup (not shown). The displayed topology of the dendrogram is based on a reconstruction using the neighbor-joining algorithm. Bootstrap values (as percentages of 1000 resampling times) based on neighbor-joining and RAxML calculations are shown in the front of each node; provided that the branching was retrieved with both methods and at least with one reconstruction method, a value of 80% or above was obtained. Type strains are indicated by a superscript T. UniProt accession numbers of the used proteins are given in parentheses. Stable phylogenetic lineages of Sox proteins are indicated by dots or vertical line drawings followed by an arbitrary designation. The shown bar represents an estimated sequence divergence of 10%.
