Total number of negatively charged residues (Asp + Glu): 13 Total number of positively charged residues (Arg + Lys): 10 Atomic composition: Carbon C 502 Hydrogen H 789 Nitrogen N 123 Oxygen O 154 Sulfur S 6 Formula: C502H789N123O154S6 Total number of atoms: 1574 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 11585 Abs 0.1% (=1 g/l) 1.034, assuming all pairs of Cys residues form cystines Ext. coefficient 11460 Abs 0.1% (=1 g/l) 1.023, 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 27.39 This classifies the protein as stable. Aliphatic index: 85.38 Grand average of hydropathicity (GRAVY): 0.143
