Reason: strain 45.9 kcal/mol
strain ΔE 45.9 kcal/mol 1 protein-contact clashes 65% of hydrophobic surface is solvent-exposed (15/23 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.
