Reason: 13 internal clashes
7 protein-contact clashes 13 intramolecular clashes 64% of hydrophobic surface is solvent-exposed (14/22 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.

🚨Solvent-exposed hydrophobic surface — desolvation penalty likely
64% of hydrophobic surface is solvent-exposed (14/22 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.
