SSPF Crystallisation Propensity Predictors

OB-Score and ParCrys
THE BARTON GROUPMore Information
Predictions to estimate a protein's propensity to form diffraction-quality crystals are calculated using the methods ParCrys and the OB-Score. ParCrys is a Parzen Window approach based on calculated isoelectric point, hydrophobicity and the frequencies of S, C, G, F, Y, M residues. For more details see Overton, Padovani, Girolami & Barton (2008). Bioinformatics 24:901-907 and the SSPF crystallisation propensity predictors information page
The OB-Score is a Z-score scale based on calculated isoelectric point and hydrophobicity. For more details, see Overton & Barton (2006). FEBS Lett. 580, 4005-4009 and the SSPF crystallisation propensity predictors information page
Note that results usually take about 3 minutes to return.
