| Total Number of Atoms: | 5685 |
| Total number of positively charged residues (ARG + LYS): | 10 |
| Total number of negatively charged residues (ASP + GLU): | 4 |
| Extinction Coefficient: | This protein does not contain any Tryptophan residues. Experience shows that this could result in more than 10% error in the computed extinction coefficient. Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 9440 Absorption 0.1% (=1 g/l) 0.230, assuming all pairs of CYS residues form cystines Ext. coefficient 8940 Absorption 0.1% (=1 g/l) 0.218, assuming all CYS residues are reduced |
| Aromaticity: | 0.067 Aromaticity is the calculated relative frequency of Phe+Trp+Tyr |
| Instability Index: | The computed Instability Index (II) is : 118.86 This indicates that the protein/peptide is unstable |
