Characterization of a membrane-bound PQQ-dependent d-lactate dehydrogenase in Gluconobacter japonicus

Applied Microbiology and Biotechnology
Membrane-bound pyrroloquinoline quinone (PQQ)–dependent quinoproteins are key components of the periplasmic oxidative metabolism of acetic acid bacteria, yet several predicted enzymes remain experimentally uncharacterized.

The Potential Role of Pyrroloquinoline Quinone to Regulate Thyroid Function and Gut Microbiota Composition of Graves’ Disease in Mice

Polish Journal of Microbiology, 2023
Graves’ disease (GD) is an autoimmune disorder disease, and its prevalence continues to increase worldwide. Pyrroloquinoline quinone (PQQ) is a naturally antioxidant compound in milk, vegetables, and meat. We aim to identify the treatment efficacy of PQQ

Enterobacter Species: Opportunistic Human and Plant Pathogens With Plant‐Beneficial Traits

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.
The pathogen profile on Enterobacter species synthesises current knowledge on host range, disease symptoms, plant‐beneficial traits and compares genomic features within the genus. ABSTRACT Enterobacter species occur across diverse habitats and are best known for causing opportunistic and nosocomial infections in humans.

Mussel‐Bioinspired Edible Ca2+‐Crosslinked Alginate Hydrogel Electrodes for Glucose Gastrointestinal Monitoring

Advanced Science, Volume 13, Issue 8, 9 February 2026.
A fully edible soft electrode is engineered from Ca2⁺‐crosslinked alginate integrated with polydopamine, silver nanoparticles, and food‐grade glucose oxidase. The hybrid hydrogel combines ionic and electronic conduction, enabling efficient glucose‐to‐H2O2 conversion and catalytic reduction in simulated intestinal fluid.

Dietary Pyrroloquinoline Quinone Addition Alleviated Weaning Stress via Modulation of Gut Microbiota and Metabolic Profiles in Weaned Piglets

Animals
Weaning stress in piglets severely restricts swine production efficiency due to growth retardation, immune suppression, and intestinal dysfunction. This study investigated the effects of dietary pyrroloquinoline quinone (PQQ) on 36 weaned piglets (22 ± 1

Cryo‐EM Analysis in CASP16

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 1, Page 447-459, January 2026.
ABSTRACT Since CASP13, experimentalists have been encouraged to provide their cryo‐EM data along with the derived atomic models to the CASP organizers to aid assessment. In CASP16, 38 cryo‐EM datasets were provided for assessment, which represented most cryo‐EM targets.

Molecular Mechanisms of Plant Growth–Promoting Rhizobacteria (PGPR) in Biofertilization and Disease Suppression of Crops

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Plant growth–promoting rhizobacteria (PGPR) are beneficial soil bacteria that colonize the rhizosphere and enhance plant growth through direct and indirect mechanisms, including nutrient solubilization, phytohormone production, suppression of phytopathogens, and activation of plant defense mechanisms.
