Application Notes
The antibody binds specifically to LeuT is a bacterial symporter specific for small hydrophobic amino acids such as leucine and alanine, driven by the sodium electrochemical gradient across the membrane. The antibody is specific for the inward-open conformation of LeuT, which required weakening of the Na2 binding site by mutating Thr 354 to Val, and Ser 355 to Ala in TM8, and the mutation of Tyr 268 to Ala in TM6 of the cytoplasmic gate. (TSY_LeuT). The Fab fragment of the antibody was obtained by papain digestion. Due to the high homology of LeuT to human neurotransmitter transporters, its crystal structure can reveal the mechanism of action of many drugs, such as antidepressants.

Note on publication
Describes the role of neurotransmitter sodium symporters (NSS) in chemical neurotransmission, and the importance of LeuT, a bacterial NSS homologue, as a structural template. Crystal structures of the outward-open and inward-open states of LeuT, stabilised by the monoclonal antibodies 2B12 and 6A10, are presented.
