Total number of negatively charged residues (Asp + Glu): 40 Total number of positively charged residues (Arg + Lys): 30 Atomic composition: Carbon C 857 Hydrogen H 1382 Nitrogen N 228 Oxygen O 285 Sulfur S 8 Formula: C857H1382N228O285S8 Total number of atoms: 2760 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 2980 Abs 0.1% (=1 g/l) 0.151 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 31.06 This classifies the protein as stable. Aliphatic index: 66.92 Grand average of hydropathicity (GRAVY): -0.820
