Detailed information of T6SS

Note: only experimentally validated proteins are displayed in the graph.


Summary

T6SS ID T6SS00002 experimental
T6SS type Type i1
Strain Vibrio cholerae O1 biovar El Tor str. N16961
Replicon (RefSeq) chromosome II (Vas) (NC_002506)
Location 110871..145577
Function -
Comment T6SS introduces cytotoxicity towards Dictyostelium and cultured mammalian macrophages. T6SS is involved in inflammatory response, diarrhoea and actin cross-linking in mouse intestine. T6SS leads to killing of E. coli, Salmonella and Citrobacter rodentium.
