Figure 2From: Developing a powerful In Silico tool for the discovery of novel caspase-3 substrates: a preliminary screening of the human proteomePhysiochemical properties of the tetrapeptide motif. The content analysis for each position in the tetrapeptide motif (P4P3P2P1) was made for all the cleaved substrates. a) Hydrophobic and hydrophilic amino acid frequencies. b) Acidic, basic, polar and non-polar amino acid frequencies.Back to article page
