To understand the origin of life, it’s essential to determine “what is life”. Biology explain that life is based on presence of organic molecules (lipids, proteins, NADH, …). In this vision of life, understanding origin of life start by determining how these molecules have been formed. During a long time, theory based on primordial soup was the explanation to demonstrate how these molecules could have been formed, however these results have been controverted and cannot answer to thermodynamics problems which postulated that any physical system like a living organism in an isolated system will dislocate without any energy source. Since then, scientists give new theories integrated these thermodynamics constraints.
From the point of view of metabolism biology and in particular bioenergetics, the hypothesis of the emergence of life as an energy conversion metabolism based on metals is more than attractive. Even if for some RNA molecules a catalytic activity has been identified, such activities are almost non-existent in the living world. On the other hand, a multitude of metabolic catalysts are made by metallo-enzymes. Molecular phylogeny data suggest that many of these metallo-enzymes were present in what is known as LUCA (Last Universal Common Ancestor), the oldest cell entity accessible to phylogenetic approaches. The active sites of many of these ancient metalloproteins have strong similarities with the metallic structures of some minerals proposed to be present at ~ 4 billion years. These intriguing similarities between the fundamental premises of the theories of metal-based inorganic metabolism on the one hand, and the structure of energy metabolism in living organisms on the other, have also been exploited more recently to refine the details of these hypotheses based on empirical observations in the field of microbial bioenergetics.
My project proposes to fill this gap with an innovative approach combining biology (phylogeny, enzymology), biophysics-chemistry, and geology to elucidated prebiotics catalytic reactions involved in the primitive metabolism.
