Protein-DNA interactions: structural, thermodynamic and clustering patterns of conserved residues in DNA-binding proteins.

Abstract excerpt

Amino acid residues, which play important roles in protein function, are often conserved. Here, we analyze thermodynamic and structural data of protein-DNA interactions to explore a relationship between free energy, sequence conservation and structural cooperativity. We observe that the most stabilizing residues or putative hotspots are those which occur as clusters of conserved residues. The higher packing...
