Reason: 15 internal clashes, strain 51.8 kcal/mol
strain ΔE 51.8 kcal/mol
15 intramolecular clashes
100% of hydrophobic surface is solvent-exposed (23/23 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.
