Extinction coefficients:
This protein does not contain any Trp 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 0
Abs 0.1% (=1 g/l) 0.000, assuming all pairs of Cys residues form cystines
Ext. coefficient 0
Abs 0.1% (=1 g/l) 0.000, assuming all Cys residues are reduced
Estimated half-life:
The N-terminal of the sequence considered is M (Met).
The estimated half-life is: 30 hours (mammalian reticulocytes, in vitro).
>20 hours (yeast, in vivo).
>10 hours (Escherichia coli, in vivo).
Instability index:
The instability index (II) is computed to be 40.85
This classifies the protein as unstable.
Aliphatic index: 142.50
Grand average of hydropathicity (GRAVY): 1.277
