Figure 3From: A novel method for evaluation and screening of caspase inhibitory peptides by the amino acid positional fitness scoreAPF score matrices of caspases. The APF score matrices indicate the interaction preferences of amino acids with (a) caspase-3, (b) caspase-7, (c) caspase-8, and (d) caspase-9 at each position (P4-P2). If an APF score is greater than 0, the amino acid tends to be favored at a given position. ΔGth (threshold value of ΔGbind) of caspases-3, -7, -8, and -9 are -11.05, -10.69, -11.03, and -12.12 kcal/mol, respectively.Back to article page
