Schematic overview of the phenylalanine and tyrosine biosynthesis pathway in Synechocystis. The native enzymes annotated in KEGG are shown in green color with corresponding genes in brackets; the genes overexpressed in this study are indicated in purple color. Question marks corresponds to genes and enzymes that have not been identified yet. Abbreviations: ADH – arogenate dehydrogenase; AT—aminotransferase; CM-chorismate mutase; DAHP—3-deoxy-D-arabino-heptulosonate-7-phosphate; E4P—erythrose-4-phosphate; HGA—homogentisate; HPC—hydroxyphenyl acetate; HPP—4-hydroxyphenylpyruvate; HPPD—4-hydroxyphenylpyruvate dioxygenase; L-Trp—L-tryptophan; PAT – prephenate aminotransferase; PDT – prephenate dehydratase; PEP—phosphoenolpyruvate; PPY -phenylpyruvate; pCou—para-coumaric acid; PQ—plastoquinone; tCA—trans-cinnamic acid; Tyr—tyrosine; α-Toc—α-Tocopherols
