Reason: 7 internal clashes
7 protein-contact clashes
7 intramolecular clashes
100% of hydrophobic surface is solvent-exposed (22/22 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.
