Glutamate transporters are integral membrane proteins that facilitate neurotransmitter uptake from the synaptic cleft into the cytoplasm of glial cells and neurons, the mechanism of transport involves transitions between extracellular- and intracellular-facing conformations; here the authors used single-molecule fluorescence resonance energy transfer imaging to directly observe conformational dynamics in trimers of a bacterial homologue of glutamate transporters that was embedded in the membrane.
