Origin of biological homochirality by crystallization of an RNA precursor on a magnetic surface

S. Furkan Ozturk et al.

Summary: Homochirality is crucial for the formation of functional polymers like RNA and peptides. Scientists have discovered that magnetic surfaces can act as chiral agents and induce enantioselective crystallization of chiral molecules, providing a prebiotically plausible way of achieving system-level homochirality. In their study, researchers achieved an unprecedented enantiomeric excess of about 60% in the spin-selective crystallization of an RNA precursor on magnetite surfaces.

The central dogma of biological homochirality: How does chiral information propagate in a prebiotic network?

S. Furkan Ozturk et al.

Summary: Biological systems are homochiral, and the question of how a racemic mixture could attain a homochiral state at the network level is addressed. The recent research shows that the chiral-induced spin selectivity effect enables the formation of homochiral crystals of the RNA precursor RAO from a racemic solution on a magnetic mineral surface. This discovery has implications for understanding the transfer of chiral information in prebiotic networks and the potential propagation of homochirality from RNA to peptides through enantioselective catalysis.

On the origins of life's homochirality: Inducing enantiomeric excess with spin-polarized electrons

S. Furkan Ozturk et al.

Summary: The origins of biological homochirality on early Earth are still unknown, but this study proposes a hypothesis regarding this phenomenon. The authors suggest that shallow closed-basin lakes on early Earth, which are expected to contain significant sedimentary magnetite deposits, could have been a plausible prebiotic environment. They hypothesize that ultraviolet (200-300 nm) irradiation of magnetite deposits could generate hydrated spin-polarized electrons that induce enantioselective prebiotic chemistry, thereby facilitating the synthesis of life's building blocks.

2D Ising Model for Adsorption-induced Enantiopurification of Racemates

Soham Dutta et al.

Summary: Research has shown that equilibrium adsorption of amino acid enantiomer mixtures onto chiral and achiral surfaces results in an amplification of surface enantiomeric excess, leading to enantiopurification of chiral adsorbates by adsorption. This process can be well-described by the 2D Ising model, which predicts the formation of homochiral monolayers from adsorption of racemic mixtures or prochiral molecules on achiral surfaces, suggesting enantiopurification without a noticeable chiral driving force.

Long-Time-Scale Magnetization Ordering Induced by an Adsorbed Chiral Monolayer on Ferromagnets

I Meirzada et al.

Summary: Through experiments, it has been demonstrated that magnetization reversal in a ferromagnet can be achieved solely by chemisorbing a chiral molecular monolayer, suggesting a long-time-scale effect attributed to exchange interactions. The study revealed a correlation between changes in the magnetization direction and changes in the tilt angle of the molecular monolayer, providing evidence for a long-time-scale characteristic of the induced magnetization reorientation under the CISS effect.

Simultaneous High-Purity Enantiomeric Resolution of Conglomerates Using Magnetic Substrates

Debkumar Bhowmick et al.

Summary: This method utilizes magnetic substrates and magnetization perpendicular to the surface to crystallize pure conglomerates of multiple molecules, based on the spin-dependent charge reorganization effect. It does not require seeding or chemical modification, and is generally applicable to any conglomerate. A system is presented for separating different enantiomers on opposite magnetized surfaces while a racemic mixture flows between them.

Interstrand Aminoacyl Transfer in a tRNA Acceptor Stem-Overhang Mimic

Long-Fei Wu et al.

Summary: Prior to the genetic coded peptide synthesis, there may have been a nonprotein-catalyzed method for generating aminoacyl-tRNA. Research shows that efficient interstrand aminoacyl transfer can occur at the 2',3'-diol terminus of a tRNA mimicking modern tRNAs in a stereoselective and chemoselective manner.

Evidence for new enantiospecific interaction force in chiral biomolecules

Yael Kapon et al.

Summary: Enantiospecific biorecognition interactions play a key role in biological events, with bio-affinity values often higher than predicted. This study presents the first direct measurement of interaction forces between chiral peptides, showing a force difference of 70 pN between same and opposite enantiomer interactions. Spin dependency and fast decay of the interaction term suggest the importance of spin and exchange interactions in biological processes.
