Na(+)- and Cl(-)-dependent taurine transporter TauT, and related proteins; solute-binding domain
This subgroup represents the solute-binding domain of TauT-like Na(+)- and Cl(-)-dependent transporters. Family members include: human TauT which transports taurine, human GAT1, GAT2, and GAT3, and BGT1, which transport gamma-aminobutyric acid (GABA), and human CT1 which transports creatine. This subgroup belongs to the solute carrier 6 (SLC6) transporter family.
Comment:based on Aquifex aeolicus LeuT (SLC6) with structure
Comment:One of two Na+ binding sites in Aquifex aeolicus LeuT. It binds the Na+ ion designated Na2, and appears conserved in Vibrio parahaemolyticus vSGLT and other SLC5 proteins
