T cell receptor (TCR) recognition of peptide-MHC (pMHC) is central to the cellular immune response. A large database of TCR-pMHC structures is needed to reveal general structural principles, such as whether the repertoire of TCR/MHC docking modes is dictated by a "recognition code" between conserved elements of the TCR and MHC genes. Although approximately 17 cocrystal structures of unique TCR-pMHC complexes have been determined, cocrystallization of soluble TCR and pMHC remains a major technical obstacle in the field. Here we demonstrate a strategy, based on NMR chemical shift mapping, that permits rapid and reliable analysis of the solution footprint made by a TCR when binding onto the pMHC surface. We mapped the 2C TCR binding interaction with its allogeneic ligand H-2Ld-QL9 and identified a group of NMR-shifted residues that delineated a clear surface of the MHC that we defined as the TCR footprint. We subsequently found that the docking footprint described by NMR shifts was highly accurate compared with a recently determined high-resolution crystal structure of the same complex. The same NMR footprint analysis was done on a high-affinity mutant of the TCR. The current work serves as a foundation to explore the molecular dynamics of pMHC complexes and to rapidly determine the footprints of many Ld-specific TCRs.
