Cholera toxin is an A-B toxin secreted by V. cholerae that causes the host cell to expel large amounts of water and ions. The toxin is made up of five identical B subunits linked to one A subunit.
The tuberculosis bacterium uses the TNT toxin to do exactly this. It acts the assassinâs blade, selectively destroying all of the NAD+ in the host cell. The enzyme âdecapitatesâ NAD+ by breaking a critical bond, separating the head from the body of the molecule.
