Completion of the cytosolic post-chorismate phenylalanine biosynthetic pathway in plants

Abstract

Phenylalanine is mostly synthesized in plant plastids, but cytosolic transamination of phenylpyruvate also contributes. Here the authors show that a cytosolic chorismate mutase and a prephenate dehydratase encoded by an isoform of the plastidial ADT3 enzyme, produce phenylpyruvate in the cytosol.
