Fig. 2.

a RmlC homodimer in complex with co-crystalized 2′-deoxy-thymidine-β-l-rhamnose (TRH) (PDB ID: 2IXC). The two monomers are colored in pink and beige, respectively. b Close view of the co-crystal ligand TRH, with His62 and His119 highlighted. TRH is colored with carbon in violet, nitrogen in blue, oxygen in red, and phosphorus in orange. Protein residues are colored with carbon in salmon, while other atoms are following the same coloring scheme as TRH. The binding surface of receptor is represented as wire frame. Hydrogen bonds are shown with dashed green lines
