Interactions between two RsbS monomers. (a) The dimer structure in an asymmetric unit. The area in the red box indicates the binding interface (interface 1) which mediates the dimerization. The RsbS pentamer in the asymmetric unit is formed by the `head-to-tail' interactions. (b) Residues at interface 1 involved in direct contacts. The residues are drawn as stick models and are labeled. (c) Dimer structure generated by crystallographic twofold symmetry. The N-termini in the dimeric unit are adjacent to each other. The area in the blue box indicates interface 2. (d) The residues involved in the dimerization on interface 2 are drawn as stick models and are labeled. Each monomer in (a)–(d) is colored differently. The N- and C-termini are labeled N and C, respectively.
