Total number of negatively charged residues (Asp + Glu): 19 Total number of positively charged residues (Arg + Lys): 24 Atomic composition: Carbon C 842 Hydrogen H 1320 Nitrogen N 234 Oxygen O 237 Sulfur S 8 Formula: C842H1320N234O237S8 Total number of atoms: 2641 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 11585 Abs 0.1% (=1 g/l) 0.617, assuming all pairs of Cys residues form cystines Ext. coefficient 11460 Abs 0.1% (=1 g/l) 0.611, 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 58.68 This classifies the protein as unstable. Aliphatic index: 75.12 Grand average of hydropathicity (GRAVY): -0.500
