Ab initio models of Hfq_Ec65–DsrA₃₄ and Hfq_Ec–DsrA₃₄ derived from the SAXS data. (A–C) Models of Hfq_Ec65 (blue) and (D–F) Hfq_Ec (green) represented with their respective solvent accessible surfaces were docked manually into the bulk region of the ab initio shapes. The Hfq_Ec65 atomic coordinates were derived from the crystal structure pdb1HK9 (7). The Hfq_Ec structure was derived from the same atomic coordinates with the C-terminal segment modelled using SAXS data (29).
