Total number of negatively charged residues (Asp + Glu): 37 Total number of positively charged residues (Arg + Lys): 40 Atomic composition: Carbon C 1274 Hydrogen H 2143 Nitrogen N 345 Oxygen O 386 Sulfur S 9 Formula: C1274H2143N345O386S9 Total number of atoms: 4157 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 7115 Abs 0.1% (=1 g/l) 0.247, assuming all pairs of Cys residues form cystines Ext. coefficient 6990 Abs 0.1% (=1 g/l) 0.243, 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 38.92 This classifies the protein as stable. Aliphatic index: 107.93 Grand average of hydropathicity (GRAVY): -0.195
