Total number of negatively charged residues (Asp + Glu): 3 Total number of positively charged residues (Arg + Lys): 2 Atomic composition: Carbon C 193 Hydrogen H 295 Nitrogen N 45 Oxygen O 57 Sulfur S 0 Formula: C193H295N45O57 Total number of atoms: 590 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 9970 Abs 0.1% (=1 g/l) 2.398 Estimated half-life: The N-terminal of the sequence considered is R (Arg). The estimated half-life is: 1 hours (mammalian reticulocytes, in vitro). 2 min (yeast, in vivo). 2 min (Escherichia coli, in vivo). Instability index: The instability index (II) is computed to be 35.54 This classifies the protein as stable. Aliphatic index: 105.26 Grand average of hydropathicity (GRAVY): 0.226
