Modern views of ancient metabolic networks [PDF]

open access: yes, 2018
Metabolism is a molecular, cellular, ecological and planetary phenomenon, whose fundamental principles are likely at the heart of what makes living matter different from inanimate one. Systems biology approaches developed for the quantitative analysis of

Radicals in prebiotic chemistry

open access: yesPure and Applied Chemistry, 2020
Abstract Radical chemistry is tightly interwoven in proposed prebiotic synthetic pathways, reaction networks and geochemical scenarios that have helped shape our understanding of how life could have originated. Gas-phase prebiotic reactions involving electric discharge, vapour ablation by asteroidal and cometary impacts as well as ...

The origins and physical roots of life’s dual – metabolic and genetic – nature [PDF]

open access: yes, 2017
This review paper aims at a better understanding of the origin and physical foundation of life’s dual – metabolic and genetic – nature. First, I give a concise ‘top-down’ survey of the origin of life, i.e., backwards in time from extant DNA/RNA/protein ...

A prebiotic chemistry inspired one-step functionalization of zwitterionic nanofiltration membranes for efficient molecular separation

open access: yesJournal of Membrane Science Letters, 2022
Loose nanofiltration (LNF) membranes have shown promises in achieving efficient separation on molecular level at relatively low pressure. In this study, a zwitterionic PES/AMN/PSBAE LNF membrane was designed by co-depositing the AMN and an in-house made ...

Twenty years of "Lipid World": a fertile partnership with David Deamer [PDF]

open access: yes, 2019
"The Lipid World" was published in 2001, stemming from a highly effective collaboration with David Deamer during a sabbatical year 20 years ago at the Weizmann Institute of Science in Israel.

Influence of Rare Earth Elements on Prebiotic Reaction Networks Resembling the Biologically Relevant Krebs Cycle

open access: yesAngewandte Chemie, EarlyView.
Rare earth elements can act as mediators in a prebiotic reaction network, producing various intermediates of the citric acid cycle starting from glyoxylate and pyruvate. The ionic radius and the resulting variation in Lewis acidity has a significant influence on the observed product scope.

Translation‐Promoting Effects of RNA Template Overhangs in the Absence of Ribosomes

open access: yesAngewandte Chemie, EarlyView.
Ribosome‐free translation of an RNA sequence into a peptide sequence can be controlled by the folding of the template strand. Overhang sequences forming a triplex structure with the templating region and the peptidoyl RNA in pH‐dependent manner increase yields up to 40‐fold through entropic effects and mixed anhydride formation, allowing for controlled,

Application of Co-bioprocessing Techniques (Enzymatic Hydrolysis and Fermantation) for Improving the Nutritional Value of Wheat Bran as Food Functional Ingrediens [PDF]

open access: yes, 2019
Last time the food industry pays the great attention to questions, connected with changing existing technologies for raising the efficacy of the raw materials complex processing and increasing the output of high-quality products and food ingredients with

Comprehensive Mapping of Compositional Dynamics in the Formose Reaction Network

open access: yesAngewandte Chemie, EarlyView.
Mass spectrometric mapping of target and non‐target products in the formose reaction network was achieved using van Krevelen diagrams and Kendrick mass defect plots. The developed visualization framework offers a powerful means to guide rational strategies for reaction control.

Remnants of an ancient metabolism without phosphate [PDF]

open access: yes, 2017
Phosphate is essential for all living systems, serving as a building block of genetic and metabolic machinery. However, it is unclear how phosphate could have assumed these central roles on primordial Earth, given its poor geochemical accessibility.
