Permease that is involved in the active transport across the cytoplasmic membrane of all three aromatic amino acids, phenylalanine, tyrosine and tryptophan. H(+)(in) + L-phenylalanine(in) = H(+)(out) + L-phenylalanine(out) H(+)(in) + L-tryptophan(in) = H(+)(out) + L-tryptophan(out) H(+)(in) + L-tyrosine(in) = H(+)(out) + L-tyrosine(out) Belongs to the amino acid-polyamine-organocation (APC) superfamily. Amino acid transporter (AAT) (TC 2.A.3.1) family.
