Table 1. The sequences of the six in silico discovered peptide pairs, their associated scores (Γscore), binding free energies per peptide (ΔG~binding), intrinsic self-aggregation propensities per peptide (P~agg), the DMD/PRIME20 simulation results, and the TEM-observed results (unit: kcal/mol).

Designs 1 to 3 result from setting λ = 3.0, while designs 4 to 6 result from setting λ = 4.0.
