Protein
Amino acid permease 6
Organism
Arabidopsis thaliana
Function
Amino acid-proton symporter. Stereospecific transporter with a broad specificity for tryptophan, proline, and neutral and acidic amino acids. Have an affinity for aspartate in a physiological range. Involved in the uptake of amino acids diffusing out of the xylem tracheids into the xylem parenchyma.
Similarity
Belongs to the amino acid/polyamine transporter 2 family. Amino acid/auxin permease (AAAP) (TC 2.A.18.2) subfamily.
