Neurotransmitter:sodium symporters (NSS) serve as targets for drugs including antidepressants and psychostimulants. Here authors report the X-ray structure of the prokaryotic NSS member, LeuT, in a Na+/substrate-bound, inward-facing occluded conformation which is a key intermediate in the LeuT transport cycle.
