In Silico Approach to Identify the Relationships between COVID-19 and Coronary Artery Disease/Rheumatoid Arthritis [PDF]

open access: yes, 2023
Global public has been threatened by the coronavirus disease 2019 (COVID-19) pandemic which led to nearly 15 million deaths around the world. People with complex and chronic diseases usually have more severe COVID-19 symptoms than the general population.

In Vitro Psilocybin Synthesis by Co‐Immobilized Enzymes

open access: yesChemistry – A European Journal, Volume 31, Issue 29, May 22, 2025.
The drug candidate and psychedelic mushroom product psilocybin was produced by multienzyme‐charged beads in a biocatalytic cell‐free approach. Using immobilized fungal indolethylamine biosynthetic and additional bacterial enzymes, these beads turned over 4‐hydroxy‐l‐tryptophan to psilocybin.

Reconstitution of Methionine Cycle With ATP Regeneration for Whole‐Cell Catalysis of Creatine Production in Engineered Escherichia coli

open access: yesMicrobial Biotechnology, Volume 18, Issue 5, May 2025.
In this study, we constructed a CR biosynthesis pathway in E. coli by introducing exogenous AGAT and GAMT. We integrated the reconstitution methionine cycle with a polyphosphate kinase‐based ATP regeneration system, achieving a CR titre of 5.27 g/L with a productivity of 0.22 g/L/h.

Nutrition-Based Modulation of Poly-ADP-Ribosylation and its possible role in Alzheimer’s disease [PDF]

open access: yes, 2015
Alzheimer’s Disease (AD) is the most common neurodegenerative disease and the main reason of dementia in the elderly. On the pathological point of view, it is characterized by extracellular aggregates of amyloid peptides and intracellular deposits of tau

Engineering Caffeic Acid O‐Methyltransferase for Efficient De Novo Ferulic Acid Synthesis

open access: yesEngineering in Life Sciences, Volume 25, Issue 4, April 2025.
ABSTRACT Ferulic acid is a high‐value chemical synthesized in plants. The ferulic acid biosynthesis is still affected by the insufficient methylation activity of caffeic acid O‐methyltransferase (COMT). In this study, we engineered COMT from Arabidopsis thaliana to match caffeic acid, and the mutant COMTN129V‐H313A‐F174L showed 4.19‐fold enhanced ...

Gene mining a marama bean expressed sequence tags (ESTs) database: Embryonic seed development genes and microsatellite marker identification [PDF]

open access: yes, 2015
Tylosema esculentum (marama bean) is one of the underutilized legumes that have potential to provide protein and fatty acids to ensure food security in dry parts of Southern Africa.

The V‐Shaped Structuring Regulated via the LuxS‐Dependent Quorum‐Sensing Pathway Is Associated With Lactiplantibacillus plantarum Survivability in Acidic Environments

open access: yesFood Frontiers, Volume 6, Issue 2, Page 801-818, March 2025.
This study elucidates how the V‐shaped multicellular structuring facilitates the 3D‐biofilm formation through the LuxS‐dependent quorum‐sensing pathway, which provides an extraordinary protection mode for cellular survivability in highly acidic conditions.

Bioalkylation Strategies to Synthesize Allylated Tetrahydroisoquinolines by Using Norcoclaurine Synthase and O‐Methyltransferases

open access: yesChemCatChem, Volume 17, Issue 4, February 17, 2025.
The cascade using methionine adenosyltransferases (MATs), O‐methyltransferases (O‐MTs), and thioadenosine nucleosidase (MTAN) was utilized for the regioselective biocatalytic O‐allylation of a variety of catechols and tetrahydroisoquinolines. (S)‐Tetrahydroisoquinoline substrates were stereoselectively generated from the catecholamine dopamine and ...

Structure of \u3cem\u3eArabidopsis thaliana\u3c/em\u3e 5-Methylthioribose Kinase Reveals a More Occluded Active Site Than its Bacterial Homolog [PDF]

open access: yes, 2007
Background: Metabolic variations exist between the methionine salvage pathway of humans and a number of plants and microbial pathogens. 5-Methylthioribose (MTR) kinase is a key enzyme required for methionine salvage in plants and many bacteria.

α‐N‐Methyltransferase regiospecificity is mediated by proximal, redundant enzyme–substrate interactions

open access: yesProtein Science, Volume 34, Issue 2, February 2025.
Abstract N‐Methylation of the peptide backbone confers pharmacologically beneficial characteristics to peptides that include greater membrane permeability and resistance to proteolytic degradation. The borosin family of ribosomally synthesized and post‐translationally modified peptides offer a post‐translational route to install amide backbone α‐N ...
