Total number of negatively charged residues (Asp + Glu): 0 Total number of positively charged residues (Arg + Lys): 0 Atom composition: As there is at least one ambiguous position (B,Z or X) in the sequence considered, the atomic composition cannot be computed. Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 5500 Abs 0.1% (=1 g/l) 6.124 Estimated half-life: The N-terminal of the sequence considered is I (Ile). The estimated half-life is: 20 hours (mammalian reticulocytes, in vitro). 30 min (yeast, in vivo). >10 hours (Escherichia coli, in vivo). Instability index: The instability index (II) is computed to be 18.43 This classifies the protein as stable. Aliphatic index: 39.00 Grand average of hydropathicity (GRAVY): -0.080
