Total number of negatively charged residues (Asp + Glu): 3 Total number of positively charged residues (Arg + Lys): 13 Atomic composition: Carbon C 339 Hydrogen H 560 Nitrogen N 92 Oxygen O 88 Sulfur S 1 Formula: C339H560N92O88S1 Total number of atoms: 1080 Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 9970 Abs 0.1% (=1 g/l) 1.354 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 31.27 This classifies the protein as stable. Aliphatic index: 102.00 Grand average of hydropathicity (GRAVY): -0.286
