3.A.23.1.1
Type VI secretion system (T6SS) VasA-L + Vca0107-09; + Vca0123 + Vc1416 (Pukatzki et al., 2006; Pukatzki et al., 2007). This secretion system displays antimicrobial properties (Macintyre et al., 2010).  It functions like contractile tails of phage and penetrates cells with a trimeric VgrG spike protein to which are associated PAAR repeat proteins that sharpen the tip of the spike and are released into the cytoplasm of the target cell (Shneider et al. 2013). Certain Vibrionaceae adapted their antibacterial T6SS to mediate interactions with eukaryotic hosts or predators, promoting their toxicity (Dar et al. 2018).
