Multiple prebiotic metals mediate translation. [PDF]
Today, Mg2+ is an essential cofactor with diverse structural and functional roles in life's oldest macromolecular machine, the translation system. We tested whether ancient Earth conditions (low O2, high Fe2+, and high Mn2+) can revert the ribosome to a ...

Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

Identification of the prebiotic translation apparatus within the contemporary ribosome [PDF]
A structural element that could have existed independently in the prebiotic era was identified at the active site of the contemporary ribosome. It is suggested to have functioned as a proto-ribosome catalyzing peptide bond formation and non-coded ...

HCV IRES manipulates the ribosome to promote the switch from translation initiation to elongation. [PDF]
The internal ribosome entry site (IRES) of the hepatitis C virus (HCV) drives noncanonical initiation of protein synthesis necessary for viral replication.

Abstract The isoproterenol‐induced myocardial infarction model is a well‐established experimental approach for studying cardiac injury and testing potential protective treatments. By overstimulating beta‐adrenergic receptors, this model closely reproduces key features of human heart attacks, including oxidative damage, calcium imbalance, inflammatory ...

tRNA Core Hypothesis for the Transition from the RNA World to the Ribonucleoprotein World
Herein we present the tRNA core hypothesis, which emphasizes the central role of tRNAs molecules in the origin and evolution of fundamental biological processes.

Cotranslational folding of proteins on the ribosome.
Many proteins in the cell fold cotranslationally within the restricted space of the polypeptide exit tunnel or at the surface of the ribosome. A growing body of evidence suggests that the ribosome can alter the folding trajectory in many different ways ...

Cyclization of Fungal Nonribosomal Peptides by a Terminal Condensation-Like Domain [PDF]
Cyclization of linear peptidyl precursors produced by nonribosomal peptide synthetases (NRPSs) is an important step in the biosynthesis of bioactive cyclic peptides. Whereas bacterial NRPSs use thioesterase (TE) domains to perform the cyclization, fungal

Hydrogel‐based microfluidic chips revolutionize drug delivery, tissue engineering, and biosensing, yet face challenges due to fragility and connection difficulty. This study introduces a novel cartridge design that enhances usability through a hydrogel–plastic hybrid design and a contactless connection method.

Filling the Gaps to Solve the Extensin Puzzle [PDF]
Extensins (EXTs) are highly repetitive plant O-glycoproteins that require several post-translational modifications (PTMs) to become functional in plant cell walls.
