Total number of negatively charged residues (Asp + Glu): 7 Total number of positively charged residues (Arg + Lys): 5 Atomic composition: Carbon C 884 Hydrogen H 1401 Nitrogen N 285 Oxygen O 294 Sulfur S 12 Formula: C884H1401N285O294S12 Total number of atoms: 2876 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) 0.071 Estimated half-life: The N-terminal of the sequence considered is Q (Gln). The estimated half-life is: 0.8 hours (mammalian reticulocytes, in vitro). 10 min (yeast, in vivo). 10 hours (Escherichia coli, in vivo). Instability index: The instability index (II) is computed to be 83.95 This classifies the protein as unstable. Aliphatic index: 52.64 Grand average of hydropathicity (GRAVY): -0.932
