N2 - A high-resolution structure of the human MHC-I molecule HLA-A*1101 is presented in which it forms a complex with a sequence homologue of a peptide that occurs naturally in hepatitis B virus DNA polymerase. The sequence of the bound peptide is AIMPARFYPK, while that of the corresponding natural peptide is LIMPARFYPK. The peptide does not make efficient use of the middle E pocket for binding, which leads to a rather superficial and exposed binding mode for the central peptide residues. Despite this, the peptide binds with high affinity (IC50 of 31 nM).
