First insights into a type II toxin-antitoxin system from the clinical isolate Mycobacterium sp. MHSD3, similar to epsilon/zeta systems. [PDF]
PLoS ONE, 2017 A putative type II toxin-antitoxin (TA) system was found in the clinical isolate Mycobacterium sp. MHSD3, a strain closely related to Mycobacterium chelonae.

Biochemical and Pharmacological Studies of Clostridium perfringens .EPSILON.-Toxin.
Nippon Saikingaku Zasshi, 1996 D型ウエルシュ菌のe毒素は, 致死, 壊死作用を有するタンパク毒素で, 本菌によるヒツジの腸性中毒症の病原因子と考えられている。本研究では, e毒素の作用機構解明の手がかりを得るため, e毒素の in vivo と in vitro における作用, さらに構造と機能について検討した。まず, e毒素をラットに投与すると末梢血管の収縮による急激な血圧上昇が認められること, さらに本毒素は, in vitro で血管, 回腸などの摘出平滑筋組織を収縮させることを明らかにした。この作用は毒素が神経系にNa+の流入を促進し, その結果, 神経伝達物質が遊離, そしてCa2+チャンネルが活性化されて引き起こされることが判明した。一方, e毒素は脳組織において1種類のシアロ糖タンパク質に特異的に結合すること ...

Clostridium perfringens epsilon toxin inhibits the gastrointestinal transit in mice
Research in Veterinary Science, 2010 Epsilon toxin produced by Clostridium perfringens type B and D is a potent toxin that is responsible for a highly fatal enterotoxemia in sheep and goats. In vitro, epsilon toxin produces contraction of the rat ileum as the result of an indirect action, presumably mediated through the autonomic nervous system.
