Total number of negatively charged residues (Asp + Glu): 17 Total number of positively charged residues (Arg + Lys): 12 Atomic composition: Carbon C 548 Hydrogen H 852 Nitrogen N 144 Oxygen O 185 Sulfur S 2 Formula: C548H852N144O185S2 Total number of atoms: 1731 Extinction coefficients: This protein does not contain any Trp residues. Experience shows that this could result in more than 10% error in the computed extinction coefficient. Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 8940 Abs 0.1% (=1 g/l) 0.716 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 25.77 This classifies the protein as stable. Aliphatic index: 67.36 Grand average of hydropathicity (GRAVY): -0.673
