Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Interplay between RNA‐protein interactions and RNA structures in gene regulation
Methodological advances in mapping transcriptome‐wide RNA‐protein interactions and RNA structures have started to uncover the potential of RNP conformations in gene regulation. Competing RNA–RNA, RNA‐protein and protein–protein interactions shape the compaction and function of RNPs throughout their lifetime and may provide novel therapeutic targets in ...

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

Overview of molecular signatures of senescence and associated resources: pros and cons
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Molecular determinants of signal transduction in tropomyosin receptor kinases
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Study on increase of nicotinamide mononucleotide yield by site-directed mutagenesis of nicotinamide phosphoribosyltransferase [PDF]
Nicotinamide phosphoribosyltransferase (NAMPT) was a key rate-limiting enzyme in the biosynthetic pathway of nicotinamide mononucleotide (NMN). In this study, the NAMPT gene derived from Comamonadaceae bacterium was heterologous expressed in Escherichia ...

Multiple site-directed mutagenesis via simple cloning by prolonged overlap extension
We describe the application of simple cloning by prolonged overlap extension for multiple site-directed mutagenesis in the same plasmid. We show that it is possible to use this technique with very short PCR templates.

Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe
Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.
