Phylobiochemical characterization of class-Ib aspartate/prephenate aminotransferases reveals evolution of the plant arogenate phenylalanine pathway.
The aromatic amino acid Phe is required for protein synthesis and serves as the precursor of abundant phenylpropanoid plant natural products. While Phe is synthesized from prephenate exclusively via a phenylpyruvate intermediate in model microbes, the alternative pathway via arogenate is predominant in plant Phe biosynthesis. However, the molecular and biochemical evolution of the plant arogena...
متن کاملRNAi suppression of Arogenate Dehydratase1 reveals that phenylalanine is synthesized predominantly via the arogenate pathway in petunia petals.
l-Phe, a protein building block and precursor of numerous phenolic compounds, is synthesized from prephenate via an arogenate and/or phenylpyruvate route in which arogenate dehydratase (ADT) or prephenate dehydratase, respectively, plays a key role. Here, we used Petunia hybrida flowers, which are rich in Phe-derived volatiles, to determine the biosynthetic routes involved in Phe formation in p...

Prephenate aminotransferase directs plant phenylalanine biosynthesis via arogenate.
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 ...
