Total number of negatively charged residues (Asp + Glu): 8 Total number of positively charged residues (Arg + Lys): 17 Atomic composition: Carbon C 383 Hydrogen H 632 Nitrogen N 106 Oxygen O 108 Sulfur S 3 Formula: C383H632N106O108S3 Total number of atoms: 1232 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 8480 Abs 0.1% (=1 g/l) 0.992, assuming all pairs of Cys residues form cystines Ext. coefficient 8480 Abs 0.1% (=1 g/l) 0.992, 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 22.96 This classifies the protein as stable. Aliphatic index: 74.68 Grand average of hydropathicity (GRAVY): -0.591
