Domain arrangement of the expressed SEO proteins. (A) The phylogenetic tree was calculated with RaxML from a T-Coffee protein alignment. Identified protein domains are drawn to scale. The positions of the SEO-NTD and SEO-CTD domains and the potential thioredoxin fold are indicated. (B) Sequence logos: M1 = sequence logo specific for all SEO proteins; M2 = sequence logo specific for SEO subgroups 1-3; M3 = sequence logo specific for SEO subgroups 5, 6 and 7; and M4 = sequence logo specific for SEO subgroups 5 and 6, with potential intrinsic disorder. The position of the individual sequence logos is also indicated in (A).
