low affinity secondary active ammonium transmembrane transporter activity
exact
OBSOLETE. Enables the transfer of ammonium from one side of a membrane to the other, up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by a chemiosmotic source of energy. Secondary active transporters include symporters and antiporters. In low-affinity transport the transporter is able to bind the solute only if it is present at very high concentrations.
