      The bacterial neurotransmitter:sodium symporter homoglogue LeuT is an well-established model system for understanding the fundamental basis for how human monoamine transporters, such as the dopamine and serotonin, couple ions with neurotransmitter uptake. Here the authors provide convincing data to show that K+ binding on the intraceullular side catalyses the return step of the transport cycle in LeuT by binding to one of the two sodium sites. The mechansitic consequences of K+ binding could either facilitate LeuT re-setting and/or prevent the rebinding and possible efflux of Na+ and substrate.
