| 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 500 Absorption 0.1% (=1 g/l) 0.025, assuming all pairs of CYS residues form cystines Ext. coefficient 0 Absorption 0.1% (=1 g/l) 0.000, assuming all CYS residues are reduced |
| Aromaticity: | 0.026 Aromaticity is the calculated relative frequency of Phe+Trp+Tyr |
| Instability Index: | The computed Instability Index (II) is : 34.38 This indicates that the protein/peptide is stable |
