Total number of negatively charged residues (Asp + Glu): 10 Total number of positively charged residues (Arg + Lys): 9 Atomic composition: Carbon C 444 Hydrogen H 695 Nitrogen N 121 Oxygen O 145 Sulfur S 8 Formula: C444H695N121O145S8 Total number of atoms: 1413 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 4720 Abs 0.1% (=1 g/l) 0.458, assuming all pairs of Cys residues form cystines Ext. coefficient 4470 Abs 0.1% (=1 g/l) 0.434, 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 40.47 This classifies the protein as unstable. Aliphatic index: 59.78 Grand average of hydropathicity (GRAVY): -0.490
