Total number of negatively charged residues (Asp + Glu): 16 Total number of positively charged residues (Arg + Lys): 18 Atomic composition: Carbon C 1193 Hydrogen H 1830 Nitrogen N 282 Oxygen O 317 Sulfur S 9 Formula: C1193H1830N282O317S9 Total number of atoms: 3631 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 48150 Abs 0.1% (=1 g/l) 1.889, assuming all pairs of Cys residues form cystines Ext. coefficient 47900 Abs 0.1% (=1 g/l) 1.880, assuming all Cys residues are reduced Estimated half-life: The N-terminal of the sequence considered is E (Glu). The estimated half-life is: 1 hours (mammalian reticulocytes, in vitro). 30 min (yeast, in vivo). >10 hours (Escherichia coli, in vivo). Instability index: The instability index (II) is computed to be 39.28 This classifies the protein as stable. Aliphatic index: 110.72 Grand average of hydropathicity (GRAVY): 0.318
