Fig. 4From: Protein production in Escherichia coli is guided by the trade-off between intracellular substrate availability and energy costControl analysis of translation elongation for varying relative concentrations of the reaction system. Here, a non-native (GFP) and a native (EFTu) gene as target protein sequences were investigated. Elasticities \(\epsilon_{EFTu \cdot tRNA}\) and FCC represent the sensitivity of the translation rate with respect to varying total ternary complex (substrate) and total ribosome (enzyme) concentration.
