Total number of negatively charged residues (Asp + Glu): 21 Total number of positively charged residues (Arg + Lys): 19 Atomic composition: Carbon C 805 Hydrogen H 1273 Nitrogen N 205 Oxygen O 229 Sulfur S 6 Formula: C805H1273N205O229S6 Total number of atoms: 2518 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 13075 Abs 0.1% (=1 g/l) 0.740, assuming all pairs of Cys residues form cystines Ext. coefficient 12950 Abs 0.1% (=1 g/l) 0.732, 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 32.66 This classifies the protein as stable. Aliphatic index: 96.46 Grand average of hydropathicity (GRAVY): -0.194
