Total number of negatively charged residues (Asp + Glu): 17 Total number of positively charged residues (Arg + Lys): 19 Atomic composition: Carbon C 618 Hydrogen H 983 Nitrogen N 165 Oxygen O 180 Sulfur S 4 Formula: C618H983N165O180S4 Total number of atoms: 1950 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 8940 Abs 0.1% (=1 g/l) 0.651 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 49.75 This classifies the protein as unstable. Aliphatic index: 85.97 Grand average of hydropathicity (GRAVY): -0.385
