in order to assess the importance of a conserved amino acid in the vdj junctional region of the beta chain of t cell receptors ( tcrs ) specific for pigeon cytochrome c , we generated t cell transfectant clones that express either a tcr identical to that of the cytochrome c-specific clone d6 or a mutated form of the d6 tcr , in which the conserved residue was replaced by one of two other amino acids .
