Amino acid synthesis through biogenetic-type CO2 fixation.
TLDR
In bacterial photosynthesis, reductive CO2 fixation was thought to proceed through activation of carboxylic acid by coenzyme A followed by the reductive incorporation of CO2 in the presence of reduced ferredoxin.Abstract:
IN bacterial photosynthesis, reductive CO2 fixation was thought to proceed through activation of carboxylic acid by coenzyme A followed by the reductive incorporation of CO2 in the presence of reduced ferredoxin (a kind of non-haem iron–sulphur protein) and an enzyme, pyruvate synthase, as shown in equation (1). The reaction takes place in vitro in the same way using CoA, reduced ferredoxin and pyruvate synthase1.read more

Mineral Surfaces, Geochemical Complexities, and the Origins of Life
TL;DR: Crystalline surfaces of common rock-forming minerals are likely to have played several important roles in life's geochemical origins and may have contributed centrally to the linked prebiotic problems of containment and organization by promoting the transition from a dilute prebiotics "soup" to highly ordered local domains of key biomolecules.

1,2-Dithiolene Complexes of Transition Metals
R.P. Burns,C.A. Mcauliffe +1 more
TL;DR: There has been a phenomenal increase in the study of the chemistry of transition metal complexes containing sulfur ligands over the past two decades as mentioned in this paper, and the major reason for this is the revitalization of chemistry of the unsaturated sulphur donor chelates.

Transition metal sulfides and the origins of metabolism
TL;DR: The history of the theory and experimental evidence that the natural catalytic and reactive qualities of transition metal sulfides are linked to primitive metabolism is reviewed in this paper, where the authors present a review of the experimental evidence supporting these theories.

TL;DR: In this paper, the results of the reductive citrate cycle (RCC) were used as a method of deducing a pathway for carbon fixation in primitive hydrothermal environments, and it was concluded that the acid catalyzed decarboxylation pathway, leading ultimately to propene and CO2, may provide the most promise for reaction network reversal under natural hydrotherm conditions.

Iron-sulfide chelates of some sulfur-containing peptides as model complex of non-heme iron proteins.
Yukio Sugiura,Hisashi Tanaka +1 more
TL;DR: The release of sulfur from some sulfur-containing peptides such as glutathione and l-mercaptopropionyl glycine and incorporation of released sulfur to iron chelate of these peptides to form peptide-iron-sulfide chelates which show ferredoxin-like absorption spectrum were confirmed by the change of the absorption spectra and the determination ofreleased sulfur.
