Arginine 445 controls the coupling between glutamate and cations in the neuronal transporter EAAC-1.

Abstract excerpt

The substrate-binding sites in membrane transporters are alternately accessible from either side of the membrane, but the molecular basis of how this alternate opening of internal and external gates is achieved is largely unknown. Here we present data indicating that, in the neuronal electrogenic sodium- and potassium-coupled glutamate transporter EAAC-1, the substrate-binding site and one of the gates, or a...
