Amino acid derivatives are substrates or non-transported inhibitors of the amino acid transporter PAT2 (slc36a2)

►PAT2 (SLC36A2) transports proline, glycine, alanine and hydroxyproline. ►Heterocyclic proline derivatives are transported substrates. ►Heterocyclic GABA derivatives are translocated slowly. ►Tryptophan derivatives (e.g. α-methyl-d,l-tryptophan) are non-transported inhibitors.
