Abstract

A tentative scheme of methanogenesis from CO2 is presented. It involves the participation of methanopterin, coenzyme FA, coenzyme M and the activated form of coenzyme M. CO2 is bound to the enamine group of methanopterin and reduced to the formyl level by an intramolecular redox reaction. Coenzyme M is activated by binding to factor F430, a nickel-tetrapyrrole present in methylcoenzyme M reductase.

产甲烷细菌的辅酶
提出了一种由二氧化碳生成甲烷的初步方案。它涉及甲烷蝶呤、辅酶FA、辅酶M和活化形式的辅酶M的参与。CO2与甲烷蝶呤的烯胺基结合,通过分子内氧化还原反应还原到甲酰基水平。辅酶M通过与F430因子结合而激活,F430是甲基辅酶M还原酶中存在的镍四吡咯。
