Total number of negatively charged residues (Asp + Glu): 13 Total number of positively charged residues (Arg + Lys): 27 Atomic composition: Carbon C 634 Hydrogen H 1071 Nitrogen N 191 Oxygen O 187 Sulfur S 6 Formula: C634H1071N191O187S6 Total number of atoms: 2089 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 4720 Abs 0.1% (=1 g/l) 0.324, assuming all pairs of Cys residues form cystines Ext. coefficient 4470 Abs 0.1% (=1 g/l) 0.307, 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 32.52 This classifies the protein as stable. Aliphatic index: 85.31 Grand average of hydropathicity (GRAVY): -0.707
