Schematic representation of FhuA Δ1-159 Exp design. Schematic picture of FhuA Δ 1-159 Exp secondary structure as it transverses the membrane (depicted in grey). Membrane spanning β-strands are marked in orange, outside loops (L1' - L11) in green and periplasmic turns (T1' - T11) in turquoise. The two N-terminal doubled β-strands as well as the associated turns and loops are depicted in red.
