Predicted General Properties of the Cytochrome c Protein (Homo sapiens) - Primary Sequence Analysis (with ProtParam)b
Number of amino acids: 105
Molecular weight: 11748.7
Theoretical pI: 9.59
Total number of negatively charged residues (Asp + Glu): 11
Total number of positively charged residues (Arg + Lys): 20
Atomic composition: Carbon C 526 Hydrogen H 845 Nitrogen N 143 Oxygen O 149 Sulfur S 6
Formula: C526H845N143O149S6
Total number of atoms: 1669
Extinction coefficients: Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water. Ext. coefficient 13075 Abs 0.1% (=1 g/l) 1.113, assuming ALL Cys residues appear as half cystines Ext. coefficient 12950 Abs 0.1% (=1 g/l) 1.102, assuming NO Cys residues appear as half cystines
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 11.38 This classifies the protein as stable.
Aliphatic index: 66.00
Grand average of hydropathicity (GRAVY): -0.706
