Figure 4
Structures of the three different PpsR PAS domain dimers including their N-caps (from PpsRΔHTH protomers A and B). The PAS core and N-cap of one protomer is coloured according protomer C in Fig. 3[link](d), whereas the second protomer is coloured in equivalent but lighter colours. (a) N-domain dimer (residues 6–120). (b) PAS1 dimer (residues 147–256). (c) PAS2 dimer (residues 264–378). The N- and C-termini of each domain are labelled.
