Protein domain organization of secretins and pilotins from Type II, Type III Secretion Systems, Type IV pili and the Tad system. Secretins of the Rhizobium (Rhc-) family of T3SSs, represented here from subgroup I Rhc-T3SS of Mesorhizobium loti and subgroup II Rhc-T3SS of Pseudomonas syringae pv phaseolicola (rows 12 and 11 respectively), are encoded by two different genes. The Rhc2 polypeptides are obviously related to the Tad system (rows 13 and 14) rather than to secretins from other T3SS families (rows 5–10). Pilotins (column 1) do not share common domains and seem to adapt very diverse folds. The domain organization analysis was based on Pfam database (Finn et al., ; http://pfam.xfam.org/), complemented by SMART (Letunic et al., ; http://smart.embl-heidelberg.de/). More than half of the N0 domains present were recognized through threading (Kelley and Sternberg, ; http://www.sbg.bio.ic.ac.uk/phyre2).
