Epitope sequence and TCR entropy correlation. A. The TCR entropy reduction profile similarities between major epitopes (epitopes with >200 paired chains, n=17) in VDJdb are plotted. The entropy reduction profile similarity falls within a range for each epitope(136 comparisons). B. Entropy profile differences are plotted against the Levenshtein distance between epitope sequences. There is a significant correlation between Levenshtein distance between epitopes and TCR entropy profile differences. A triad of 3 epitopes, AVFDRKSDAK, KLGGALQAK, and RLRAEAQVK, has the smallest difference by entropy profile (linear regression). C. Entropy profiles for the most differential k-mers are shown for epitopes KLGGALQAK and AVFDRKSDAK together, and KLGGALQAK and DATYQRTRALVR (arbitrary units, linear scale). D. Entropy reduction analysis was performed using MIRA TCR chains, showing the same trends (n=61, 1830 comparisons, linear regression). See also Fig. S6.
