Stoichiometry of sodium- and chloride-coupled glycine transport in synaptic plasma membrane vesicles derived from rat brain.
The stoichiometric properties of the glycine transporter were studied in synaptic plasma membrane vesicles from rat brain. The present results, together with previous data from our laboratory, allow us to suggest a stoichiometry of 2 Na+ and 1 Cl- per glycine zwitterion for the translocation cycle catalyzed by the glycine carrier. We propose a kinetic model with an ordered mechanism for the binding/debinding of solutes.
