CcmS specifically interacts with the C-terminal extension of the carboxysome shell protein CcmK1 [1,2]. Upon binding to CcmS, this C-terminal segment of CcmK1 folds into an amphipathic alpha-helix protruding outward and likely functions as a hinge to crosslink adjacent CcmK1-4 hexamers, thereby facilitating precise assembly of the beta-carboxysome shell [2].
