Total number of negatively charged residues (Asp + Glu): 30 Total number of positively charged residues (Arg + Lys): 26 Atomic composition: Carbon C 1200 Hydrogen H 1915 Nitrogen N 299 Oxygen O 365 Sulfur S 7 Formula: C1200H1915N299O365S7 Total number of atoms: 3786 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 15595 Abs 0.1% (=1 g/l) 0.586, assuming all pairs of Cys residues form cystines Ext. coefficient 15470 Abs 0.1% (=1 g/l) 0.582, 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 43.58 This classifies the protein as unstable. Aliphatic index: 91.10 Grand average of hydropathicity (GRAVY): 0.002
