Estimated half-life:

The N-terminal of the sequence considered is A (Ala).

The estimated half-life is: 4.4 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 29.36
This classifies the protein as stable.



Aliphatic index: 77.10

Grand average of hydropathicity (GRAVY): -0.183
