aTotal number of hydrophobic amino acids: alanine, leucine, isoleucine, valine, proline, phenylalanine, tyrosine, tryptophan, and methionine.

bTotal number of charged amino acids: asparagine, glutamate, arginine, and lysine.

cTotal number of polar amino acids: asparagine, glutamine, serine, threonine, and cysteine.

dTotal number of negatively charged amino acids: asparagine and glutamate.

eTotal number of positively charged amino acids: arginine and lysine.

fAI – The aliphatic index of proteins is defined as the relative volume occupied by aliphatic side chains (alanine, valine, isoleucine, and leucine)

pI, principle isoelectric point; neg, negative; pos, positive; AI, aliphatic index; H bonds, hydrogen bonds; Rc, rigid clusters; #Rc, total number of sites in rigid cluster; df, total independent degrees of freedom.
