Intellectual frameworks to understand complex biochemical systems at the origin of life

B Seelig, IA Chen - Nature Chemistry, 2025 - nature.com
Understanding the emergence of complex biochemical systems, such as protein translation,
is a great challenge. Although synthetic approaches can provide insight into the potential …

Gradual evolution of a homo-L-peptide world on homo-D-configured RNA and DNA

E Węgrzyn, I Mejdrová, T Carell - Chemical Science, 2024 - pubs.rsc.org
Modern life requires the translation of genetic information–encoded by nucleic acids–into
proteins, which establishes the essential link between genotype and phenotype. During …

Initial amino acid: codon assignments and strength of codon: anticodon binding

M Su, SJ Roberts, JD Sutherland - Journal of the American …, 2024 - ACS Publications
The ribosome brings 3′-aminoacyl-tRNA and 3′-peptidyl-tRNAs together to enable
peptidyl transfer by binding them in two major ways. First, their anticodon loops are bound to …

RNA‐Templated Peptide Bond Formation Promotes L‐Homochirality

E Węgrzyn, I Mejdrová, FM Müller… - Angewandte Chemie …, 2024 - Wiley Online Library
The world in which we live is homochiral. The ribose units that form the backbone of DNA
and RNA are all D‐configured and the encoded amino acids that comprise the proteins of all …

Selective Nonenzymatic Formation of Biologically Common RNA Hairpins

LF Wu, J Zhang, R Cornwell‐Arquitt… - Angewandte …, 2025 - Wiley Online Library
The prebiotic formation of RNA building blocks is well‐supported experimentally, yet the
emergence of sequence‐and structure‐specific RNA oligomers is generally attributed to …

RNA‐Vermittelte Peptidbindungen Fördern die L‐Homochiralität

E Węgrzyn, I Mejdrová, FM Müller… - Angewandte …, 2024 - Wiley Online Library
Die Welt, in der wir leben, ist homochiral. Die Riboseeinheiten, die das Rückgrat von DNA
und RNA bilden, sind alle D‐konfiguriert, und die kodierten Aminosäuren, aus denen die …

RNA-directed Peptide synthesis across a nicked loop

M Su, S Roberts, J Sutherland - 2024 - chemrxiv.org
Ribosomal translation at the origin of life requires controlled aminoacylation to produce
mono-aminoacyl esters of tRNAs. Herein, we show that transient annealing of short RNA …

Covalent Linkages Used in Prebiotic Chemistry for RNA‐Templated Amino Acid Transfer and Peptide Synthesis

L Escobar - ChemSystemsChem, 2024 - Wiley Online Library
Biological translation is a universal process taking place in the ribosome. It involves the
synthesis of a protein with a particular sequence from the information encoded in a …

Cross-catalytic enhancement of peptides and RNA from a common prebiotic activated intermediate

R Roy, AA Sawant, S Rajamani - bioRxiv, 2024 - biorxiv.org
Previous origin of life studies have demonstrated the presence of amino acids and
nucleotides in the same prebiotic milieu. In this study, we set out to understand the interplay …
