Phosphoenolpyruvate/phosphate translocator that transports phosphoenolpyruvate (PEP), 2-phosphoglycerate, 3-phosphoglycerate and dihydroxyacetone phosphate. Imports PEP to the chloroplast stroma as one substrate of the shikimate pathway, from which aromatic amino acids and a variety of secondary products derive. Required for correct leaf mesophyll cell development and expression of chlorophyll a/b binding protein 3 (CAB3). Expressed in root columella, lateral root cap and root vasculature tissue. In leaves, highly expressed in xylem parenchyma cells. In flowers, expressed in sepals, petals, filaments of the stamens, anthers and stigma. Reticulate leaf phenotype. Reduced number of leaf palisade mesophyll cells and increased bundle sheath cells. Small chloroplasts in mesophyll cells. Reduced photosynthetic electron transport rate. Under-expression of CAB3 protein. Reduced levels of aromatic amino acids and phenolic compounds derived from shikimate pathway. Belongs to the TPT transporter family. PPT (TC 2.A.7.9) subfamily.
