APC superfamily

The amino acid-polyamine-organocation (APC) superfamily is the second largest superfamily of secondary carrier proteins currently known, and it contains several Solute carriers. Originally, the APC superfamily consisted of subfamilies under the transporter classification number (TC # 2.A.3). This superfamily has since been expanded to include eighteen different families.
