Total number of negatively charged residues (Asp + Glu): 15 Total number of positively charged residues (Arg + Lys): 16 Atomic composition: Carbon C 749 Hydrogen H 1161 Nitrogen N 191 Oxygen O 214 Sulfur S 8 Formula: C749H1161N191O214S8 Total number of atoms: 2323 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 24075 Abs 0.1% (=1 g/l) 1.457, assuming all pairs of Cys residues form cystines Ext. coefficient 23950 Abs 0.1% (=1 g/l) 1.450, 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 45.84 This classifies the protein as unstable. Aliphatic index: 76.49 Grand average of hydropathicity (GRAVY): -0.289
