C4-dicarboxylate transporters of the Tellurite-resistance/Dicarboxylate Transporter (TDT) family
This subfamily contains bacterial C4-dicarboxylate transporters, which is part of the Tellurite-resistance/Dicarboxylate Transporter (TDT) family. It includes Tellurite resistance protein tehA; the tehA gene encodes an integral membrane protein that has been shown to have efflux activity of quaternary ammonium compounds. TehA protein of Escherichia coli functions as a tellurite-resistance uptake permease.
Comment:Mutational and structural studies in Haemophilus influenzae TehA (HiTehA) show that this residue plays a crucial role in gating of the anion channel
