- Abstract
The aromatic amino acids L-phenylalanine and L-tyrosine and their plant-derived natural products are essential in human and plant metabolism and physiology. Here we identified Petunia hybrida and Arabidopsis thaliana genes encoding prephenate aminotransferases (PPA-ATs), thus completing the identification of the genes involved in phenylalanine and tyrosine biosyntheses. Biochemical and genetic characterization of enzymes showed that PPA-AT directs carbon flux from prephenate toward arogenate, making the arogenate pathway predominant in plant phenylalanine biosynthesis.
