Total number of negatively charged residues (Asp + Glu): 60 Total number of positively charged residues (Arg + Lys): 57

Atomic composition:

Carbon C 1875 Hydrogen H 3103 Nitrogen N 541 Oxygen O 580 Sulfur S 14

Formula: C1875H3103N541O580S14 Total number of atoms: 6113

Extinction coefficients:

Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water.

Ext. coefficient 10220 Abs 0.1% (=1 g/l) 0.238, assuming all pairs of Cys residues form cystines


Ext. coefficient 9970 Abs 0.1% (=1 g/l) 0.232, 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 32.87 This classifies the protein as stable.


Aliphatic index: 95.06

Grand average of hydropathicity (GRAVY): -0.296
