About T4EffPred

T4EffPred is a web server which can predict effector proteins secreted by Type IV secretion systems of Gram-negative bacteria. This predictor was developed by computing four classes of sequence features such as amino acid composition, residue pair composition, PSSM composition and auto covariance transformation of PSMM profiles to train a SVM_based classification model. On benchmark tests, the predictor can discriminate type-IVA effectors and non-effectors with overover 93% accuracy and discriminate type-IVB effectors and non-effectors with overover 95% accuracy . It is the firstly anounced de vovo predictor which can widely predict effectors in Gram-negetive bactericial genomes.
