Estimated half-life:

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

The estimated half-life is: 1.4 hours (mammalian reticulocytes, in vitro).
                            3 min (yeast, in vivo).
                            >10 hours (Escherichia coli, in vivo).


Instability index:

The instability index (II) is computed to be 32.03
This classifies the protein as stable.



Aliphatic index: 79.47

Grand average of hydropathicity (GRAVY): -0.314
