Total number of negatively charged residues (Asp + Glu): 34 Total number of positively charged residues (Arg + Lys): 41 Atomic composition: Carbon C 1027 Hydrogen H 1641 Nitrogen N 323 Oxygen O 319 Sulfur S 5 Formula: C1027H1641N323O319S5 Total number of atoms: 3315 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 11920 Abs 0.1% (=1 g/l) 0.501, assuming all pairs of Cys residues form cystines Ext. coefficient 11920 Abs 0.1% (=1 g/l) 0.501, 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 47.18 This classifies the protein as unstable. Aliphatic index: 59.11 Grand average of hydropathicity (GRAVY): -1.272
