Total number of negatively charged residues (Asp + Glu): 31 Total number of positively charged residues (Arg + Lys): 22 Atomic composition: Carbon C 1037 Hydrogen H 1585 Nitrogen N 289 Oxygen O 328 Sulfur S 15 Formula: C1037H1585N289O328S15 Total number of atoms: 3254 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 38180 Abs 0.1% (=1 g/l) 1.602, assuming all pairs of Cys residues form cystines Ext. coefficient 37930 Abs 0.1% (=1 g/l) 1.592, 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 49.00 This classifies the protein as unstable. Aliphatic index: 53.29 Grand average of hydropathicity (GRAVY): -0.607
