Total number of negatively charged residues (Asp + Glu): 2 Total number of positively charged residues (Arg + Lys): 1 Atomic composition: Carbon C 59 Hydrogen H 94 Nitrogen N 14 Oxygen O 21 Sulfur S 2 Formula: C59H94N14O21S2 Total number of atoms: 190 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 1490 Abs 0.1% (=1 g/l) 1.065, assuming all pairs of Cys residues form cystines Ext. coefficient 1490 Abs 0.1% (=1 g/l) 1.065, 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 61.36 This classifies the protein as unstable. Aliphatic index: 65.00 Grand average of hydropathicity (GRAVY): -0.575
