obsolete sulfur-containing amino acid secondary active transmembrane transporter activity (obsolete GO:1901680)
OBSOLETE. Enables the transfer of sulfur-containing amino acid 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.
