Figure 5From: A novel method for evaluation and screening of caspase inhibitory peptides by the amino acid positional fitness scoreThe scatter of the APF score vs log Ki for the peptides in Table 1. The solid line is the result of a linear regression fit, and r denotes correlation coefficient. (a) caspase-3, (b) caspase-7, (c) caspase-8, and (d) caspas-9.Back to article page
