WebMar 24, 2024 · The type VI secretion system (T6SS) is a double-tubular nanomachine widely found in gram-negative bacteria. Its spear-like Hcp tube is capable of penetrating a neighboring cell for cytosol-to-cytosol protein delivery. However, gram-positive bacteria have been considered impenetrable to such T6SS action. WebV. cholerae employs T6SS to kill Escherichia coli, Dictyostelium discoideum amoebae, and macrophage cell lines (2, 11, 12). Three proteins secreted by the V. cholerae T6SS belong to the VgrG family of proteins and one of these (VgrG1) carries an enzymatically active domain that is capable of cross-linking actin in eukaryotic cells (5, 11, 13).
