Reason: 9 protein-contact clashes, 9 internal clashes
9 protein-contact clashes 9 intramolecular clashes 78% of hydrophobic surface is solvent-exposed (14/18 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.
