Relative transcript levels for genes from carbon central metabolism for L-Phe overproducing strains. Metabolic network showing the relative gene transcription levels of genes related to the carbon central metabolism, fermentative pathways and the connection with the common aromatic amino acid pathway. Most relevant transcriptional responses in L-Phe overproducing strains are shown: JM101-ev2 (first value), PB12-ev2 (second value) and PB13-ev3 (third value), as compared to JM101. Metabolites abbreviations are depicted in Figure 3 legend.
