Total number of negatively charged residues (Asp + Glu): 4 Total number of positively charged residues (Arg + Lys): 19 Atomic composition: Carbon C 363 Hydrogen H 617 Nitrogen N 105 Oxygen O 93 Sulfur S 1 Formula: C363H617N105O93S1 Total number of atoms: 1179 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 4470 Abs 0.1% (=1 g/l) 0.561 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 15.55 This classifies the protein as stable. Aliphatic index: 96.00 Grand average of hydropathicity (GRAVY): -0.370
