The current model of VMAT function proposes that the efflux of two protons (H+) against the H+ gradient is coupled with influx of one monoamine. (wikipedia.org)
The first H+ efflux generates a transporter conformation associated with a high-affinity amine-binding site in the cytosolic phase, and the second H+ efflux is coupled with a second large conformational change that leads to amine transport from the cytosolic side into the vesicle, reducing amine-binding affinity. (wikipedia.org)
