Polar interactions in the C-CggR ligand-binding site. Polar interaction network of FBP (A), DHAP (B), G6P (C) and F6P (D) in the C-CggR ligand-binding site (interactions shown as green dashed lines). Parameters describing C-CggR—ligand interactions are summarized in Table S1. The amino acid residues forming the effector-binding site and contacting ligands are highly conserved in CggR homologues (Fig. S2). We therefore surmise that ligand specificities and interactions are conserved in homologous CggR-like repressors present in other Gram-positive bacteria.
