1BD2 - PubMed Abstract: 
The three-dimensional structure of a human alphabeta T cell receptor (TCR), B7, bound to the HLA-A2 molecule/HTLV-1 Tax peptide complex was determined by x-ray crystallography. Although different from the A6 TCR, previously studied, in 16 of the 17 residues that contact HLA-A2/Tax, the B7 TCR binds in a similar diagonal manner, only slightly tipped and rotated, relative to the A6 TCR ...
