Emergence Of A Potentially Ancestral ATP-synthesizing Activity Under Prebiotic Amino Acid Constraints
The earliest enzymes are thought to have been composed of the limited amino acid repertoire available on prebiotic Earth. However, how such compositional simplicity shaped catalytic capability remains unclear.

Reduction Of NAD and NMN On Mineral Surfaces With H2 Reveals A Functional Role For The Adenosine Moiety In Prebiotic Evolution
Many cofactors share a molecular structure – adenosine – that otherwise occurs in nucleic acids. The presence of adenosine in cofactors has presented an evolutionary puzzle.
