Total number of negatively charged residues (Asp + Glu): 51 Total number of positively charged residues (Arg + Lys): 33 Atomic composition: Carbon C 1300 Hydrogen H 2067 Nitrogen N 351 Oxygen O 425 Sulfur S 12 Formula: C1300H2067N351O425S12 Total number of atoms: 4155 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 29005 Abs 0.1% (=1 g/l) 0.973, assuming all pairs of Cys residues form cystines Ext. coefficient 28880 Abs 0.1% (=1 g/l) 0.969, 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 35.59 This classifies the protein as stable. Aliphatic index: 83.85 Grand average of hydropathicity (GRAVY): -0.550
