Abstract
The roles of methanofuran and tetrahydromethanopterin as carriers of C1 moieties in the reduction of carbon dioxide to methane were studied in representatives of diverse groups of methanogens, confirming that these roles, first reported for Methanobacterium thermoautotrophicum, are common for methanogenesis in general. Extracts of the methanogens tested converted formyl-methanofuran and methyl-tetrahydromethanopterin to methane; the extractable cofactors derived from the same methanogens, with one exception, complemented a methanofuran- and tetrahydromethanopterin-deficient enzyme system from M. thermoautotrophicum. The amounts of extractable methanofuran and tetrahydromethanopterin were determined for each representative methanogen.
