Abstract
Reduction of CO2 to formate utilizing formate dehydrogenases (FDHs) has been attempted biologically and electrochemically. However, the conversion efficiency is very low due to the low energy potential of electron donors and/or electron competition with other electron acceptors. To overcome such a low conversion efficiency, I focused on a direct electron transfer between two unrelated redox enzymes for the efficient reduction of CO2 and utilized the quantum mechanical magnetic properties of the [Fe-S] ([iron-sulfur]) cluster to develop a novel electron path. Using this electron path, we connected non-interacting carbon monoxide dehydrogenase and FDH, constructing a synthetic carbon monoxide:formate oxidoreductase as a single functional enzyme complex in the previous study. Here, a theoretical hypothesis that can explain the direct electron transfer phenomenon based on the magnetic properties of the [Fe-S] cluster is proposed.
期刊介绍：
FEMS Microbiology Letters gives priority to concise papers that merit rapid publication by virtue of their originality, general interest and contribution to new developments in microbiology. All aspects of microbiology, including virology, are covered.
2019 Impact Factor: 1.987, Journal Citation Reports (Source Clarivate, 2020)
Ranking: 98/135 (Microbiology)
The journal is divided into eight Sections:
Physiology and Biochemistry (including genetics, molecular biology and ‘omic’ studies)
Food Microbiology (from food production and biotechnology to spoilage and food borne pathogens)
Biotechnology and Synthetic Biology
Pathogens and Pathogenicity (including medical, veterinary, plant and insect pathogens – particularly those relating to food security – with the exception of viruses)
Environmental Microbiology (including ecophysiology, ecogenomics and meta-omic studies)
Virology (viruses infecting any organism, including Bacteria and Archaea)
Taxonomy and Systematics (for publication of novel taxa, taxonomic reclassifications and reviews of a taxonomic nature)
Professional Development (including education, training, CPD, research assessment frameworks, research and publication metrics, best-practice, careers and history of microbiology)
If you are unsure which Section is most appropriate for your manuscript, for example in the case of transdisciplinary studies, we recommend that you contact the Editor-In-Chief by email prior to submission. Our scope includes any type of microorganism - all members of the Bacteria and the Archaea and microbial members of the Eukarya (yeasts, filamentous fungi, microbial algae, protozoa, oomycetes, myxomycetes, etc.) as well as all viruses.
