Figure 3: Superposition of two binary complex structures. a, Structural difference between the complex with rA-Phe (blue) and that with the product peptide (green). b, Detailed structural difference of the Gln 188 side chains between the two structures. c, Superposition of the two complexes. The complex with rA-Phe and that with the product peptide are coloured blue and dark green, respectively. The benzyl group of rA-Phe and the Arg in the product peptide are coloured cyan and green, respectively, and are shown in stick models.
