Total number of negatively charged residues (Asp + Glu): 11 Total number of positively charged residues (Arg + Lys): 33 Atomic composition: Carbon C 676 Hydrogen H 1146 Nitrogen N 216 Oxygen O 189 Sulfur S 1 Formula: C676H1146N216O189S1 Total number of atoms: 2228 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) 0.194 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 46.28 This classifies the protein as unstable. Aliphatic index: 81.91 Grand average of hydropathicity (GRAVY): -0.678
