| 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 4970 Absorption 0.1% (=1 g/l) 0.146, assuming all pairs of CYS residues form cystines Ext. coefficient 4470 Absorption 0.1% (=1 g/l) 0.131, assuming all CYS residues are reduced |
| Aromaticity: | 0.077 Aromaticity is the calculated relative frequency of Phe+Trp+Tyr |
| Instability Index: | The computed Instability Index (II) is : 37.58 This indicates that the protein/peptide is stable |
