Total number of negatively charged residues (Asp + Glu): 22 Total number of positively charged residues (Arg + Lys): 43 Atomic composition: Carbon C 957 Hydrogen H 1593 Nitrogen N 279 Oxygen O 280 Sulfur S 6 Formula: C957H1593N279O280S6 Total number of atoms: 3115 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 22460 Abs 0.1% (=1 g/l) 1.036, assuming all pairs of Cys residues form cystines Ext. coefficient 22460 Abs 0.1% (=1 g/l) 1.036, 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 55.35 This classifies the protein as unstable. Aliphatic index: 71.75 Grand average of hydropathicity (GRAVY): -0.971
