Overview of the SortPred methodology











SortPred consists of two separate prediction layers. Both the benchmark and independent datasets for Layer 1 consists of sortases and non- sortases, where as Layer 2 comprises the sequences representing each sortase class. In both these layers, five composition and property-based features (AAC, CTD, CTriad, DPC & QSO) and their hybrids are utilized in a 10-fold cross validation using RF to select the best models from each layer. For Layer 2 SMOTE algorithm is used to handle the imbalance data during cross-validation. For each layer, the performance of the selected models are evaluated on the independent datasets separately. Finally, if the sequence is predicted to be as a sortase enzyme, this information is passed to Layer 2 for predicting the sortase class.
