SBT2 is conserved during the course of evolution from bacteria to embryophytes. (a) Comparative structural analysis of the homology-modelled SBT2 protein between Colwellia psychrerythraea, Mesotaenium endlicherianum, Physcomitrella patens, and Arabidopsis thaliana or Oryza sativa by superimposition. The colors corresponding to individual species are labelled in the figure. (b) The compiled analysis of the SBT2 protein among all the above-mentioned species by using the CONSURF tool. The pink color at the core region indicates the highly conserved nature of SBT2 throughout evolution (left panel). The right panel displays the multiple sequence alignment of the representative protein sequence from the five species along with the information regarding secondary structures revealing conserved amino acid blocks.
