Term Name: | high-affinity secondary active ammonium transmembrane transporter activity |
---|---|
Synonyms: | high affinity secondary active ammonium transmembrane transporter activity |
Definition: | 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 high-affinity transport the transporter is able to bind the solute even if it is only present at very low concentrations. |
