Total number of negatively charged residues (Asp + Glu): 11 Total number of positively charged residues (Arg + Lys): 29 Atomic composition: Carbon C 710 Hydrogen H 1181 Nitrogen N 197 Oxygen O 199 Sulfur S 3 Formula: C710H1181N197O199S3 Total number of atoms: 2290 Extinction coefficients: This protein does not contain any Trp residues. Experience shows that this could result in more than 10% error in the computed extinction coefficient. Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 11920 Abs 0.1% (=1 g/l) 0.756 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 26.36 This classifies the protein as stable. Aliphatic index: 91.41 Grand average of hydropathicity (GRAVY): -0.354
