Total number of negatively charged residues (Asp + Glu): 4 Total number of positively charged residues (Arg + Lys): 20 Atomic composition: Carbon C 1169 Hydrogen H 1847 Nitrogen N 273 Oxygen O 283 Sulfur S 8 Formula: C1169H1847N273O283S8 Total number of atoms: 3580 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 38975 Abs 0.1% (=1 g/l) 1.590, assuming all pairs of Cys residues form cystines Ext. coefficient 38850 Abs 0.1% (=1 g/l) 1.585, 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 39.51 This classifies the protein as stable. Aliphatic index: 135.21 Grand average of hydropathicity (GRAVY): 0.794
