Efficient Production of L-Threonine by E. coli Using High-Throughput Screening and Multi-Enzyme Complex Engineering

open access: yesFermentation
To enhance the L-threonine synthesis level in Escherichia coli, this study constructed screening markers rich in L-threonine rare codons. By replacing all the threonine codons in the protein sequences with a high proportion of threonine with L-threonine ...

Liquid–Liquid Phase Separation in Major Hallmarks of Cancer

open access: yesCell Proliferation, Volume 59, Issue 2, February 2026.
Aberrant condensates formed through phase separation are involved in the dysregulation of various critical cellular processes, including genome stability, transcriptional regulation and signal transduction, thereby promoting malignant transformation and the acquisition of multiple cancer hallmarks.

Bidirectional Communication Between Astrocytes and Neurons via Extracellular Vesicles: A Multi‐Omics Approach

open access: yesJournal of Neurochemistry, Volume 170, Issue 2, February 2026.
Schematic diagram illustrating the communication between mouse hippocampal astrocytes and neurons through extracellular vesicles (EVs). The illustration highlights unique proteins secreted by each cell type within EVs, with vesicle size proportional to the concentration of secreted proteins.

Carbohydrate restriction drives greater perturbations in circulating metabolites than low energy availability in elite male athletes

open access: yesPhysiological Reports, Volume 14, Issue 3, February 2026.
Elite male race walkers underwent a 5 d dietary intervention of either high carbohydrate (HCHO), low‐carbohydrate high‐fat (LCHF), or low energy availability (LEA) to evaluate their metabolomic response. Following a standardized 25 km endurance walk, blood samples were collected across five timepoints, ranging from a fasted state to 3 h post‐exercise ...

Design of a Multienzyme Derived from Mouse Fatty Acid Synthase for the Compartmentalized Production of 2‐Pyrone Polyketides

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
A multienzyme was formed and evaluated by covalently linking 4‐coumarate ligase (4CL1) from Piper methysticum to a non‐reducing murine fatty acid synthase. 4CL1 acylates the acyl carrier protein (ACP). The ketosynthase (KS) was engineered to accept the non‐native cinnamoyl substrate, which is elongated by malonyl‐CoA loaded via the malonyl‐acetyl ...

Evolutionary analysis of the TPP-dependent enzyme family [PDF]

open access: yes, 2008
The evolutionary relationships of the thiamine pyrophosphate (TPP)-dependent family of enzymes was investigated by generation of a neighbor joining phylogenetic tree using sequences from the conserved pyrophosphate (PP) and pyrimidine (Pyr) binding ...

Polyhydroxybutyrate accumulation by a Serratia sp [PDF]

open access: yes, 2008
A strain of Serratia sp. showed intracellular electron-transparent inclusion bodies when incubated in the presence of citrate and glycerol 2-phosphate without nitrogen source following pregrowth under carbon-limitation in continuous culture.

Functional properties, structural studies and chemoenzymatic synthesis of oligosaccharides [PDF]

open access: yes
Oligosaccharides offer beneficial effects on immune system and gut health, such as anticancer activity, immunomodulatory activity, and complement activation. Functional oligosaccharides are widely found in plants, algae, bacteria and higher fungi.
