Table 3: Overall residue propensities. The chameleon propensities calculated with the reduced resolution residue sets HPC and HP+\(-\) are shown in Tables 5 and 6. In the HPC set residues are clustered into Hydrophobic, Polar and Charged sets while in the HPC+- set the clusters include Hydrophobic, Polar, Positive and Negative.
