Kingdom-wide Discovery of Type VI Secretion Effectors via AI Uncovers Three New Bacterial Toxins
The type VI secretion system (T6SS) is a molecular harpoon used by 19% of bacteria to inject toxic proteins into microbial or host cells. Despite its widespread distribution, many T6SS effector (T6Es) genes remain unidentified. Here, we developed an XGBoost classifier integrating 42 genetic and biochemical features to identify novel T6Es. Applying our model to 2,559 T6SS-encoding bacterial…
