The chemical process catalyzed by Carbon Monoxide Dehydrogenase is referred to as a water-gas shift reaction.
CO2 reduction requires quick and efficient electron transfers to deliver necessary electrons to a redox catalyst. Therefore, a variety of electron donors/receivers (Shown as "A" and "AH2" in the reaction equation above) are observed in micro-organisms which utilize CODH. Several examples of electron transfer cofactors include Ferredoxin, NADP+/NADPH and flavoprotein complexes like flavin adenine dinucleotide (FAD). [9] [10] [11]
Microbial organisms (Both Aerobic and Anaerobic) encode and synthesize CODH for the purpose of carbon fixation (CO oxidation and CO2 reduction). Depending on attached accessory proteins (A,B,C,D-Clusters), serve a variety of catalytic functions, including reduction of [4Fe-4S] clusters and insertion of Nickel. [12]
Based on the microbe's environmental conditions, different metal complex centers are synthesized. Aerobic carboxydotrophic bacteria utilize Copper (Cu),Molybdenum (Mo) and Iron (Fe) based flavoenzymes. Anaerobic bacteria utilize Nickel (Ni) and Iron (Fe) based CODHs due to their oxygen sensitive nature. [13]
Homodimeric Ni-CODH consists of five metal complexes referred to as clusters. ..., each differing in individual coordination geometry, presence of Nickel, and location of the active site in either sub-unit α or β. [14]
Carbon monoxide dehydrogenase's or bio-mimetic complexes based on its catalytic potential in the formation of CO from CO2, shows potential future catalytic uses in industrial processes. Potential candidates include the production of CH3OH ( Acetic acid) from CO in processes found in the Cativa process and Monsanto process . Production of CO as a precursor for liquid hydrocarbons, in the Fischer-Trophsch process. [15]
Carbon Monoxide dehydrogenase is closely associated with the regulation of atmospheric CO and CO2 levels, maintaining optimal CO levels suitable for other forms of life. [16] [17] Microbial organisms rely on these enzymes for both energy conservation along with CO2 fixation. Often encoding for and synthesizing multiple unique forms of CODH for designated use. Further research into specific types of CODH show CO being used and condensed with CH3 ( Methyl groups) to form Acetyl-CoA. [18] Anaerobic micro-organisms like Acetogens undergo the Wood-Ljungdahl Pathway, relying on CODH to produce CO by reduction of CO2 needed for the synthesis of Acetyl-CoA from a methyl, coenzyme a (CoA) and corrinoid iron-sulfur protein. [19] Other types show CODH being utilized to generate a proton motive force for the purposes of energy generation. CODH is used for the CO oxidation, producing two protons which are subsequently reduced to form dihydrogen (H2, known colloquially as molecular hydrogen), providing the necessary free energy to drive ATP generation.
