high-affinity sulfate transmembrane transporter activity

Term ID

GO:0015381

Synonyms

• high affinity sulfate permease activity
• high affinity sulfate transmembrane transporter activity
• high affinity sulphate permease activity

Definition

Enables the secondary active high affinity transfer of sulfate from one side of a membrane to the other. Secondary active transport is the transfer of a solute across a membrane, 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 thesolute even if it is only present at very low concentrations.
