Methyl-coenzyme M reductase (MCR) is the key enzyme in methane formation by methanogenic Archaea. It converts the thioether methyl-coenzyme M and the thiol coenzyme B into methane and the heterodisulfide of coenzyme M and coenzyme B. The catalytic mechanism of MCR and the role of its prosthetic group, the nickel hydrocorphin coenzyme F(430), is still disputed, and no intermediates have been observed
甲基辅酶 M 还原酶 (MCR) 是产甲烷古细菌形成甲烷的关键酶。它将硫醚甲基辅酶 M 和硫醇辅酶 B 转化为甲烷和辅酶 M 和辅酶 B 的杂二硫化物。 MCR 的催化机制及其辅基镍氢卟啉辅酶 F(430) 的作用仍存在争议,并且当酶与天然底物一起温育时,迄今为止通过快速光谱技术还没有观察到中间体。在竞争性抑制剂辅酶 M 代替甲基辅酶 M 存在的情况下,将辅酶 B 添加到活性 Ni(I) 状态 MCR(red1) 诱导两个新物种,称为 MCR(red2a) 和 MCR(red2r),它们已被表征通过脉冲 EPR 光谱。在这里,我们表明辅酶 B 的 S-甲基-和 S-三氟甲基类似物也可以诱导两个 MCR(red2) 信号。 MCR(red2a) 和 MCR(red2r) 诱导的 (19)F-ENDOR 数据S-CF(3)-辅酶 B 表明,与辅酶 B 类似物结合后,辅酶 B 的 7-硫代庚酰基链的末端向

The invention relates to the field of biological fungicides with a broad range of antifungal activity coming from plant extracts from the order of Brassicales or molecules revealing similar chemical structure. In particular, Applicants surprisingly provided a new usage of a combination of sulfonyl and sulfinyl containing aliphatic glucosinolates, their by-products and synthetic analogues as efficient antifungal compounds with broad spectrum of activity.
