Figure 4

The minimum spanning tree recolored to show each index's similarity to one of two substitution matrices. Specifically, the spanning tree of size, charge, and hydrophobicity (Figure 2) is recolored to indicate whether each amino acid index is more highly correlated with the PAM74-100 amino acid substitution matrix (green) or a matrix of amino acids' proximity within the standard genetic code [8] (brown).
