Sequence Properties

Calculates some attributes based on the protein sequence.

Options

Sequence Field: Field containing the sequences
AAComp: Creates one field per amino acid codon containing the percentage of this codon in the whole sequence.
pI: Calculates the sequence based pI. (Ref: http://isoelectric.ovh.org/files/practise-isoelectric-point.html)
nRes: Total number of residues.
MolWeight: Protein weight in kilo Daltons.
nRes+: Number of positively charged residues.
nRes-: Number of negatively charged residues.
Hydrophobicity: Hydrophobicity based on J. Kyte, R.F. Doolittle, J Mol Biol 157, 105, 1982.
Aliphatic Index: Ikai, A.J. (1980) Thermostability and aliphatic index of globular proteins. J. Biochem. 88, 1895-1898
GRAVY: Kyte, J. and Doolittle, R.F. (1982) A simple method for displaying the hydropathic character of a protein. J. Mol. Biol. 157, 105-132
Polarizability: Sum of residue polarizabilities based on Marcel Swart; Journal of Computational Methods in Sciences and Engineering 4(2004) 419-425. Please note that polarizabity varies with conformation!
