The most recommended for studies about hydrophobic proteins. All predictions and limits in this software have been calculated with this scale.
GvH1.- von Heijne,G. (1992) J. Mol. Biol. 225, 487-94
Considered to improve the GES scale with prokaryotic proteins.
KD.- Kyte,J., Doolitle,R.F. (1982) J. Mol. Biol. 157, 105-32
This escale is based upon water-to-vapor transfers, and gives good results when the transfer of free energy is really important.
PA.- Persson, B., Argos, P. (1994) J. Mol. Biol. 237, 182-192
This scale, which is double, takes into account the propensity for a residue to be localised in the core or in the boundaries of a transmembrane domain. Prediction of the transmembrane segments is done following a method which differs slightly from the trapezoid method.
AMPHI.- Jähnig, F. (1990) Trends Biochem. Sci. 15, 93-95
This is an algorithm that uses the KD scale to search amphiphilic a-helices and ß-sheets.
