Figure 8: The ability of P. aeruginosa EF-Tu to function in poly(U)-directed protein synthesis. The assays were as described under Section 2. Concentrations of EF-Tu were varied between 0.25 and 3.0 μM, and concentrations of ribosomes were held constant at 0.2 μM. “Phe Incorporated” represents the amount of phenylalanine incorporated into peptides during protein synthesis.
