Total number of negatively charged residues (Asp + Glu): 9 Total number of positively charged residues (Arg + Lys): 25 Atomic composition: Carbon C 536 Hydrogen H 905 Nitrogen N 159 Oxygen O 148 Sulfur S 2 Formula: C536H905N159O148S2 Total number of atoms: 1750 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 11460 Abs 0.1% (=1 g/l) 0.954 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 26.94 This classifies the protein as stable. Aliphatic index: 91.39 Grand average of hydropathicity (GRAVY): -0.537
