Abstract excerpt

The proton-dependent oligopeptide transporter (POT/PTR) family shares a highly conserved E1X1X2E2RFXYY (E1X1X2E2R) motif across all kingdoms of life. This motif is suggested to have a role in proton coupling and active transport in bacterial homologs. For the plant POT/PTR family, also known as the NRT1/PTR family (NPF), little is known about the role of the E1X1X2E2R motif. Moreover, nothing is known about the...
