Neuronal and glial glutamate transporters limit the action of excitatory amino acids after their release during synaptic transmission. Recent structural and functional investigations have revealed much about the transport and conducting mechanisms of members of the sodium-coupled symporter family responsible for glutamate clearance in the nervous system. In this review we summarize emerging views on the general structure, binding sites for substrates and coupled ions, and transport mechanisms of mammalian glutamate transporters, integrating results from a large body of work on carrier structure-function relationships with several crystal structures obtained for the archaeal ortholog, Glt(Ph).

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Ligand-Gated Ion Channel Receptor: Gating Mechanism
The Significance of Membrane Transport
Transporters facilitate either an active or passive movement of solutes. They can allow a single-molecule transport down its...
