Detailed information of T6SS
Note: only experimentally validated proteins are displayed in the graph.
Summary
T6SS ID | T6SS00004 ![]() |
T6SS type | Type i1 |
Strain | Pseudomonas aeruginosa PAO1 |
Replicon (RefSeq) | chromosome (H2-T6SS) (NC_002516) |
Location | 1797958..1827821 |
Function | anti-eukaryotic; anti-bacterial; effector translocation; virulence |
Comment | H2-T6SS modulates internalization in epithelial cells; virulence in the worm model; virulence (slow killing) in Caenorhabditis elegans model; PldA achieves its antibacterial activity by degrading phosphatidylethanolamine; PldA contributes to the internalization of P. aeruginosa into Human Epithelial Cells and activates the PI3K/Akt Pathway during P. aeruginosa Infection. |
