Abstract

The chemical reactions that formed the building blocks of life at origins required catalysts, whereby the nature of those catalysts influenced the type of products that accumulated. Recent investigations have shown that at 100 °C awaruite, a Ni 3 Fe alloy that naturally occurs in serpentinizing systems, is an efficient catalyst for CO 2 conversion to formate, acetate, and pyruvate. These products are identical with the intermediates and products of the acetyl-CoA pathway, the most ancient CO 2 fixation pathway and the backbone of carbon metabolism in H 2 -dependent autotrophic microbes. Here, we show that Ni 3 Fe nanoparticles prepared via the hard-templating method catalyze the conversion of H 2 and CO 2 to formate, acetate and pyruvate at 25 °C under 25 bar. Furthermore, the 13 C-labeled pyruvate can be further converted to acetate, parapyruvate, and citramalate over Ni, Fe, and Ni 3 Fe nanoparticles at room temperature within one hour. These findings strongly suggest that awaruite can catalyze both the formation of citramalate, the C5 product of pyruvate condensation with acetyl-CoA in microbial carbon metabolism, from pyruvate and the formation of pyruvate from CO 2 at very moderate reaction conditions without organic catalysts. These results align well with theories for an autotrophic origin of microbial metabolism under hydrothermal vent conditions.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Only the acetyl-CoA pathway operates in vitro to form formate, acetate and pyruvate from H2 and CO2 without enzymes or cofactors, using only metals or minerals that occur in hydrothermal vents as catalysts.

    “Moreover, only one of those seven, again only the acetyl CoA pathway, operates in vitro to form its main products – formate, acetate and pyruvate [49, 90] – from H2 and CO2 without enzymes or cofactors, using only metals or minerals that occur in hydrothermal vents as catalysts [60, 61, 62, 63, 64, 125].”
  • The products produced are similar to the intermediates formed in the Acetyl-CoA pathway of autotrophic microbes, such as formate and acetate.

    “The products produced are similar to the intermediates formed in the Acetyl-CoA pathway of autotrophic microbes, such as formate and acetate [9,103].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
