Reason: 6 internal clashes
6 protein-contact clashes 6 intramolecular clashes 71% of hydrophobic surface is solvent-exposed (12/17 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.
