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 37.27
This classifies the protein as stable.
Aliphatic index: 87.78
