| As there is at least one ambiguous position (B, J, X or Z) in the sequence considered, the atomic composition cannot be computed. |
| Total number of positively charged residues (ARG + LYS): | 68 |
| Total number of negatively charged residues (ASP + GLU): | 64 |
| Extinction Coefficient: | Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 120015 Absorption 0.1% (=1 g/l) 1.664, assuming all pairs of CYS residues form cystines Ext. coefficient 119640 Absorption 0.1% (=1 g/l) 1.659, assuming all CYS residues are reduced |
| Aromaticity: | 0.110 Aromaticity is the calculated relative frequency of Phe+Trp+Tyr |
| Instability Index: | The computed Instability Index (II) is : 35.57 This indicates that the protein/peptide is stable |
