Extinction coefficients:

Extinction coefficients are in units of  M-1 cm-1, at 280 nm measured in water.

Ext. coefficient    27430
Abs 0.1% (=1 g/l)   1.487, assuming all pairs of Cys residues form cystines


Ext. coefficient    26930
Abs 0.1% (=1 g/l)   1.460, 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 30.99
This classifies the protein as stable.



Aliphatic index: 69.04

Grand average of hydropathicity (GRAVY): -0.852
