Kurzfassung:
Formylmethanofuran dehydrogenase from methanogenic Archaea catalyzes the reversible conversion of CO 2 and methanofuran to formylmethanofuran, which is an intermediate in methanogenesis from CO 2 a biological process yielding approximately 0.3 billion tons of CH 4 per year. With the enzyme from Methanosarcina barkeri , it is shown that CO 2 rather than HCO 3 is the active species of ‘CO 2 ’ utilized by the dehydrogenase. Evidence is also presented that the enzyme catalyzes a methanofuran‐dependent exchange between CO 2 and the formyl group of formylmethanofuran. The results are consistent with N ‐carboxymethanofuran being an intermediate in CO 2 reduction to formylmethanofuran.
