Total number of negatively charged residues (Asp + Glu): 0 Total number of positively charged residues (Arg + Lys): 2 Atomic composition: Carbon C 187 Hydrogen H 325 Nitrogen N 51 Oxygen O 52 Sulfur S 2 Formula: C187H325N51O52S2 Total number of atoms: 617 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 0 Abs 0.1% (=1 g/l) 0.000, assuming all pairs of Cys residues form cystines Ext. coefficient 0 Abs 0.1% (=1 g/l) 0.000, 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 40.85 This classifies the protein as unstable. Aliphatic index: 142.50 Grand average of hydropathicity (GRAVY): 1.277
