Toxin–antitoxin (TA) systems are widespread bacterial immune systems that confer protection against various environmental stresses. TA systems have been classified into eight types (I–VIII) based on the nature and mechanism of action of the antitoxin ...

Chaperone addiction of toxin–antitoxin systems
Some bacterial toxin-antitoxin systems consist of a labile antitoxin that inhibits a toxin, and a chaperone that stabilizes the antitoxin. Here, Bordes et al.

An oxygen-sensitive toxin–antitoxin system
Classical toxin–antitoxin systems in bacteria are based on silencing of a toxin by an antitoxin that, when inactivated, releases the toxin, resulting in a change in metabolism. Here, the authors characterize an oxygen-sensitive toxin–antitoxin system and

Postbooster Antibodies from Humans as Source of Diphtheria Antitoxin
Diphtheria antitoxin for therapeutic use is in limited supply. A potential source might be affinity-purified antibodies originally derived from plasma of adults who received a booster dose of a vaccine containing diphtheria toxoid. These antibodies might

Much of the diversity of prokaryotic genomes is contributed by the tightly controlled recombination activity of transposons (Tns). The Tn3 family is arguably one of the most widespread transposon families.

Immunological Characterization and Neutralizing Ability of Monoclonal Antibodies Directed Against Botulinum Neurotoxin Type H. [PDF]
BackgroundOnly Clostridium botulinum strain IBCA10-7060 produces the recently described novel botulinum neurotoxin type H (BoNT/H). BoNT/H (N-terminal two-thirds most homologous to BoNT/F and C-terminal one-third most homologous to BoNT/A) requires ...
