Abstract

In order to establish a system for structural studies of the murine class I major histocompatibility antigen complex (MHC) H-2Kd, a bacterial expression system and in vitro refolding preparation of the complex of H-2Kd with human β2m and the immunodominant peptide SYVNTNMGL from hepatitis B virus (HBV) core-protein residues 87–95 was employed. The complex (45 kDa) was crystallized; the crystals belong to space group P2221, with unit-cell parameters a = 89.082, b = 110.398, c = 47.015 Å, α = β = γ = 90°. The crystals contain one complex per asymmetric unit and diffract X-­rays to at least 2.06 Å resolution. The structure has been solved by molecular replacement and is the first crystal structure of a peptide–H-2Kd complex.
