Schematic representation of domains of RsbR and RsbS proteins and design of several deletions along with the protein–protein interaction results of the bacterial two-hybrid (BTH/BACTH) assay. (a) The RsbR protein (298 amino acids long) contains a C terminal "STAS" domain (amino acids 174–285) and five (numbered 1 to 5) major coiled-coil (CC) regions distributed along the polypeptide as revealed using the "coils" tool available on Expasy. The amino acid numbers for start and end of ‘CC’ regions are as follows: 1. 30–43; 2. 83–96; 3. 123–136; 4. 159–173; 5. 275–289. Several RsbR deletions (names are given on the right-hand side of every scheme) are also shown along with their BTH (BACTH) interaction results with RsbR, RsbS and RsbT proteins. DN and DC refer to deletion at the N- and C-terminals, respectively. (b) The RsbS protein (129 amino acids long) mostly consists of a "STAS" domain (first 112 amino acids). The deletion scheme shows progressive 43 amino acids deletion either from N terminus (RsbSDN1 and RsbSDN2) or from the C terminus (RsbSDC1 and RsbSDC2). Right panel shows a summary of the BTH (BACTH) results. Note that full length RsbS is required for its interaction with RsbR and RsbT. In both panels A and B, plus and minus signs refers to interaction or no interaction based on Fig. S4. For details see main text.
