Plastid amino acid transport

Reticulata weaves the metabolic net

In plants, de novo synthesis of all three basic amino acids (Arg, His and Lys) occurs entirely in the plastid stroma. Therefore, export of these essential primary metabolites via membrane-intrinsic proteins of the plastid envelope is crucial for plant growth, development and fitness.
