Noble Carbon Monoxide:Formate Oxidoreductase Comprising Fe-S Fusion Protein, and Use thereof

摘要

The present invention relates to a Fe-S fusion protein in which two or more Fe-S proteins having an electron transport function are linked, a novel carbon monoxide: formic acid oxidation / reductase, and a method for producing formic acid using the same. Carbon monoxide: formate oxidoreductase (CFOR) of the present invention is a CO-dehydrogenase (CODH) and formic acid dehydrogenase (formate dehydrogenase) by mediating Fe-S fusion protein derived from Fe-S protein ) By physically binding directly, electrons generated from CO dehydrogenase can be directly transferred to formic acid dehydrogenase through the Fe-S cluster of Fe-S fusion protein. In the conversion of carbon dioxide (CO
