Extinction coefficients:

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

Ext. coefficient    18910
Abs 0.1% (=1 g/l)   1.017

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 51.94
This classifies the protein as unstable.



Aliphatic index: 71.40

Grand average of hydropathicity (GRAVY): -0.851
