Total number of negatively charged residues (Asp + Glu): 31 Total number of positively charged residues (Arg + Lys): 26 Atomic composition: Carbon C 915 Hydrogen H 1432 Nitrogen N 256 Oxygen O 292 Sulfur S 5 Formula: C915H1432N256O292S5 Total number of atoms: 2900 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 16055 Abs 0.1% (=1 g/l) 0.770, assuming all pairs of Cys residues form cystines Ext. coefficient 15930 Abs 0.1% (=1 g/l) 0.764, assuming all Cys residues are reduced 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 48.97 This classifies the protein as unstable. Aliphatic index: 74.55 Grand average of hydropathicity (GRAVY): -0.897
