Localisation of the C-terminal domain of At -VirD4, in TraB CT and in LvhB4. (A) SAXS model of TraBCT dimer (transparent red surface) superimposed with the At-VirB4-Cter atomic model (in ribbons and CPK representations). The black cross indicates the two-fold symmetry axis of the dimeric TraBCT model. (B) SAXS model of LvhB4 monomer (transparent green surface) superimposed with the At-VirB4-Cter atomic model (in ribbons representation); two SAXS models of LvhB4 monomer were fitted into the TraBFL SAXS model (transparent yellow surface). The At-VirB4-Cter monomers were manually fitted into the TraBCT and LvhB4 models.
