SBC + Normalized ASAs	0.7468 +/−0.0004	0.8253 +/−0.0007
SBC + Physicochemical (PC) property	0.7424 +/−0.0007	0.820 +/−0.001
SBC + Predicted secondarystructure	0.7374 +/−0.0004	0.8185 +/−0.0008
All together	0.796 +/−0.001	0.8526 +/−0.0008

Performance is measured in terms of AUC (mean ± Std) evaluated from five repetitions of five-fold cross-validation. SBC method indicates the sequence features that adapted from the SRCPred method (12).
