Total Number of Atoms:176


Total number of positively charged residues (ARG + LYS):2
Total number of negatively charged residues (ASP + GLU):0
Extinction Coefficient:As there are no Tryptophan, Tyrosine or Cysteine in the region considered, your protein should not be visible by UV spectrophotometry.
Aromaticity:0.091

Aromaticity is the calculated relative frequency of Phe+Trp+Tyr
Instability Index:The computed Instability Index (II) is : 39.33

This indicates that the protein/peptide is stable
