An amino acid substitution determining G3m(g).

説明

An allotypic G3m(g) marker-specific substitution was studied by sequence analysis of glycopeptides derived from myeloma proteins Ba (G3m(g+)) and Bu (G3m(g-)). The experimental results indicate that glutamic acid at position 295 is responsible for the specificity. Based on the results of chemical modification (Arg, Tyr, and Glu), this antigenic epitope is presumed to involve five sequential residues from Arg-292 to Tyr-296.
