Total number of negatively charged residues (Asp + Glu): 15 Total number of positively charged residues (Arg + Lys): 11 Atomic composition: Carbon C 471 Hydrogen H 776 Nitrogen N 132 Oxygen O 156 Sulfur S 2 Formula: C471H776N132O156S2 Total number of atoms: 1537 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) 0.412 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 63.92 This classifies the protein as unstable. Aliphatic index: 99.47 Grand average of hydropathicity (GRAVY): -0.766
