Computational T3SS substrate predictions for proteins experimentally tested in this study.

aThis model could be run at more stringent (selective) or less stringent (sensitive) settings. Symbols in this column indicate that the protein was classified as a T3SS substrate at: (+) the selective level, (+/−) the sensitive level, or (−) neither level.bThis model could be run using either an ANN or SVM classifer. Symbols in this column indicate that the protein was classified as a T3SS substrate using: (+/−) ANN, (−/+) SVM, (+/+) both, or (−/−) neither classifiers.
