Figure 6.
Illustration of the contacts involving the ternary complex, the GAC and the SRL. (A) A ribbon representation of the tryptophanyl complex (red: EF-Tu, pink: tRNATrp green: L11; light blue: RNA in the GAC; dark blue: SRL. (B) Illustration of the binding residues of EF-Tu (58 and 84) and the SRL (nts 2661–2663), shown in a different orientation from (A). (C) Stereo view of superimposed three ternary complexes together with the GAC and the SRL. Purple: phenylalanyl complex; orange: tryptophanyl complex; green: leucyl complex.
