VAS1-mediated nitrogen reshuffling in aromatic amino acid homeostasis

Abstract

Aromatic amino acids (AAAs) are essential for synthesis of proteins and numerous plant natural products, yet how plants maintain AAA homeostasis remains poorly understood. Wu et al. reported that the aminotransferase VAS1 plays a role in AAA homeostasis by transferring nitrogen from AAAs to non-proteinogenic amino acids, 3-carboxytyrosine and 3-carboxyphenylalanine.
