Interfacial residues. The sequence of the HFBI chain A is given with interfacial residues shown by colored squares. Interfacial residues in the crystal structure were identified using ePISA  and are shown in green. Protein-protein and protein-graphite contact residues are highlighted in red and cyan respectively. As described in the Method Sections, the distance cutoff (dc) was set to 4.5 Å and 4.0 Å for the definition of the protein-protein and protein-graphite contacts respectively.
