label: low-affinity zinc ion transmembrane transporter activity
label_lc: low-affinity zinc ion transmembrane transporter activity
description: "Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: Zn2+ = Zn2+, probably powered by proton motive force. In low-affinity transport the transporter is able to bind the solute only if it is present at very high concentrations."
