Identification of the proteins composing the CO dehydrogenase and furfurylformamide dehydrogenase enzymes purified from a thermophilic ethane-oxidizing microbial consortium

Project description:Identification of the peptides composing the enriched multisubunit enzymes natively purified from the microbial enrichment, based on gel bands obtained by native electrophoresis. The anaerobic oxidation of alkanes is a microbial process occurring in deep-sea hydrocarbon seeps that plays a key ecological role in these exotic niches. The metabolic capacity of anaerobic ethane oxidation, involving uncharted biochemistry, was reported in two archaeal species depending on sulfate-reducing partner bacteria. This study deciphers the molecular basis of the CO2-generating steps of ethanotrophy by characterising the native archaeal enzymes isolated from a thermophilic enrichment. While other microorganisms couple these steps to ferredoxin reduction, we found that the CO-dehydrogenase and the formylmethanofuran-dehydrogenase are bound to F420-reductase modules. The crystal structures of these multi-metalloenzyme complexes revealed electronic bridges coupling C1-oxidation to F420-reduction. Accordingly, both systems exhibit robust F420-reductase activities, which are not detected in methanogenic or methanotrophic relative organisms. We speculate that the whole catabolism of these archaea is reoriented towards F420-reduction, which facilitates the electron transfer to the sulfate-reducing partner, therefore representing the driving force of ethanotrophy.

Gene expression of M. acetivorans producing ANME-1 Mcr during growth on methane vs. growth on methanol

Project description:Our goal is to convert methane efficiently into liquid fuels that may be more readily transported. Since aerobic oxidation of methane is less efficient, we focused on anaerobic processes to capture methane, which are accomplished by anaerobic methanotrophic archaea (ANME) in consortia. However, no pure culture capable of oxidizing and growing on methane anaerobically has been isolated. In this study, Methanosarcina acetivorans, an archaeal methanogen, was metabolically engineered to take up methane, rather than to generate it. To capture methane, we cloned the DNA coding for the enzyme methyl-coenzyme M reductase (Mcr) from an unculturable archaeal organism from a Black Sea mat into M. acetivorans to effectively run methanogenesis in reverse. The engineered strain produces primarily acetate, and our results demonstrate that pure cultures can grow anaerobically on methane.
