Total number of negatively charged residues (Asp + Glu): 18 Total number of positively charged residues (Arg + Lys): 25 Atomic composition: Carbon C 780 Hydrogen H 1299 Nitrogen N 233 Oxygen O 234 Sulfur S 5 Formula: C780H1299N233O234S5 Total number of atoms: 2551 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 7115 Abs 0.1% (=1 g/l) 0.399, assuming all pairs of Cys residues form cystines Ext. coefficient 6990 Abs 0.1% (=1 g/l) 0.392, 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 47.49 This classifies the protein as unstable. Aliphatic index: 94.00 Grand average of hydropathicity (GRAVY): -0.363
