Here, we characterize the four DUF1814-family nucleotidyltransferase-like toxins (MenT 1–4) encoded by the human pathogen Mycobacterium tuberculosis. An antitoxin is an antibody with the ability to neutralize a specific toxin. Antitoxins are produced by certain animals, plants, and bacteria in response to toxin exposure. Although they are most effective in neutralizing toxins, they can also kill bacteria and other microorganisms. Antitoxins are made within organisms, and can be injected into other organisms, including humans, to treat an infectio…
