Fig. 2
Overall structure of the core icosahedral structure of the stressosome. a View down the fivefold axis of the core icosahedral structure of the L. monocytogenes stressosome. Only the STAS domains of RsbR and RsbS are shown, in cyan blue and red ribbon representation, respectively. b Side view of the core icosahedral structure of the stressosome. This view is derived from the view in panel (a) by a 90° rotation along the horizontal axis. Representation of proteins is as in (a). c Schematic diagram of the core icosahedron (upper panel) and structure of the primary trimer of dimers (lower panel). In the upper panel, each protein is represented as a ball, cyan blue for RsbR and red for RsbS. The primary trimer of dimers of RsbR and RsbS onto which the entire structure is based is shown within the dashed circle, the molecular details of which are shown in the lower panel. d Structure of the primary trimer of dimers is shown in ribbon representation, with RsbR and RsbS color-coded cyan blue and red, respectively
