Abstract

The heavy chain of class I molecules of the major histocompatibility complex forms the binding site for antigenic peptides. We describe the binding of a synthetic peptide to the purified heavy chain of the human major histocompatibility complex molecule HLA-A2. The peptide binding capacity is found to be markedly increased if the protein is first partly denatured by reduction of its disulfide bonds in detergent and subsequently renatured by reoxidation. In the presence of certain detergents, the heavy chain binds peptides even when the protein is partly unfolded.
