Total number of negatively charged residues (Asp + Glu): 14 Total number of positively charged residues (Arg + Lys): 19 Atomic composition: Carbon C 654 Hydrogen H 1068 Nitrogen N 190 Oxygen O 198 Sulfur S 7 Formula: C654H1068N190O198S7 Total number of atoms: 2117 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 3105 Abs 0.1% (=1 g/l) 0.207, assuming all pairs of Cys residues form cystines Ext. coefficient 2980 Abs 0.1% (=1 g/l) 0.199, 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 44.47 This classifies the protein as unstable. Aliphatic index: 82.63 Grand average of hydropathicity (GRAVY): -0.262
