Total number of negatively charged residues (Asp + Glu): 24 Total number of positively charged residues (Arg + Lys): 45 Atomic composition: Carbon C 1402 Hydrogen H 2263 Nitrogen N 415 Oxygen O 414 Sulfur S 9 Formula: C1402H2263N415O414S9 Total number of atoms: 4503 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 51005 Abs 0.1% (=1 g/l) 1.602, assuming all pairs of Cys residues form cystines Ext. coefficient 50880 Abs 0.1% (=1 g/l) 1.598, 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 39.97 This classifies the protein as stable. Aliphatic index: 81.81 Grand average of hydropathicity (GRAVY): -0.603
