3.
The mechanisms of toxicity toward target cells exhibited by T6SS substrates are diverse, but tend to involve targeting of highly conserved bacterial structures, including degradation of the cell wall through amidase or glycohydrolase activity, disruption of cell membranes through lipase activity or pore formation, cleavage of DNA, and degradation of the essential metabolite NAD +.
