UniProt Comments
Amino acid-proton symporter. Stereospecific transporter with a broad specificity for histidine, arginine, glutamate and neutral amino acids, favoring small amino acids such as alanine, asparagine and glutamine. Accepts also large aromatic residues such as in phenlalanine or tyrosine. Has a much higher affinity for basic amino acids as compared with AAP1. May function in xylem-to-phloem transfer and in uptake of amino acids assimilated in the green silique tissue.
