Total number of negatively charged residues (Asp + Glu): 11 Total number of positively charged residues (Arg + Lys): 31 Atomic composition: Carbon C 712 Hydrogen H 1141 Nitrogen N 203 Oxygen O 183 Sulfur S 1 Formula: C712H1141N203O183S1 Total number of atoms: 2240 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 11460 Abs 0.1% (=1 g/l) 0.739 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 22.07 This classifies the protein as stable. Aliphatic index: 73.75 Grand average of hydropathicity (GRAVY): -0.557
