Figure 4
Overall structure of apo PigF. (a) The structure of the PigF homodimer. The helices, sheets and loops of monomer A are shown in blue, violet and green, respectively; monomer B is coloured grey. Secondary-structure elements involved in the dimer interface are labelled. (b) Chain A of PigF; helices, sheets and loops are shown in blue, violet and green, respectively. (c) Chain B of PigF, which lacks residues 117–152; helices are coloured blue, strands are coloured violet and loops are shown in green.
