From: Coevolution of amino acid residues in the key photosynthetic enzyme Rubisco

The amino acid composition of residues inferred as coevolving for different biochemical properties: (A) polarity, (B) Grantham distance, (C) charge and (D) volume, as shown by symbols "plus", "triangle", "rhombus" and "cross', respectively. The amino acids are ordered according to their frequency in all RBCL sequences, (as shown by "circle").
