| Extinction Coefficient: | As there are no Tryptophan, Tyrosine or Cysteine in the region considered, your protein should not be visible by UV spectrophotometry. |
| Aromaticity: | 0.000
Aromaticity is the calculated relative frequency of Phe+Trp+Tyr |
| Instability Index: | The computed Instability Index (II) is : 55.31
This indicates that the protein/peptide is unstable |
