Reason: 10 protein-contact clashes, 10 internal clashes, strain 48.8 kcal/mol
strain ΔE 48.8 kcal/mol
10 protein-contact clashes
10 intramolecular clashes
81% of hydrophobic surface is solvent-exposed (13/16 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.
