The E/C alpha- and beta-subunits of intra-I-region recombinants were analyzed for primary structural variation by comparative tryptic peptide mapping. The E/C alpha-polypeptides from B10.A, B10.A (3R) and B10.A (5R) showed complete coincident elution of peptides; the E/C beta-chains from B10.A and 3R (or 5R) were approximately 40% different. This suggests that the structural gene for the E/C beta-polypeptide is within the I-A subregion.
通过比较胰蛋白酶肽图谱分析I区内重组体的E/Cα和β亚基的一级结构变异。来自B10.A、B10.A(3R)和B10.A(5R)的E/Cα多肽显示出肽的完全一致洗脱;来自B10.A和3R(或5R)的E/Cβ链大约有40%的差异。这表明E/Cβ多肽的结构基因位于I-A亚区内。
