Effects of Electric Potential Treatment of a Chromium Hexacyanoferrate Modified Biosensor Based on PQQ-Dependent Glucose Dehydrogenase

Sensors, 2010
A novel potential treatment technique applied to a glucose biosensor that is based on pyrroloquinoline quinone (PQQ)-dependent glucose dehydrogenase (GDH) and chromium hexacyanoferrate (CrHCF) incorporated into a platinum (Pt) electrode was demonstrated.

Mutants of Escherichia coli producing pyrroloquinoline quinone [PDF]

Journal of General Microbiology, 1991
In glucose minimal medium a PTS- strain of Escherichia coli [delta (ptsH ptsI crr)] could grow slowly (doubling time, d = 10 h). When the population reached 5 x 10(6) to 2 x 10(7) cells ml-1, mutants growing rapidly (d = 1.5 h) appeared and rapidly outgrew the initial population.

The Role of Wnt Signaling in Age‐Related Alveolar Bone Loss and Regeneration

Journal of Periodontal Research, Volume 61, Issue 3, Page 237-255, March 2026.
The graphical abstract summarizes key signaling pathways involved in bone formation and resorption associated with Wnt signaling across young and aged long bone and jaw tissues. Levels of evidence are indicated as robust, moderate, or emerging, reflecting the current experimental support in each context.

Role of Two Methanol Dehydrogenases in Methanol Metabolism of Methylobacterium

Shipin gongye ke-ji
In this study, the pyrroloquinoline quinone (PQQ) high-yield mutant J1-1 of Methylobacterium glucophilum MP688 was used to do bioinformatics analysis to extract the two methanol dehydrogenase (MDH) genes from the genome, mpq0771 and mpq2496.

Altering pyrroloquinoline quinone nutritional status modulates mitochondrial, lipid, and energy metabolism in rats. [PDF]

PLoS ONE, 2011
We have reported that pyrroloquinoline quinone (PQQ) improves reproduction, neonatal development, and mitochondrial function in animals by mechanisms that involve mitochondrial related cell signaling pathways.

Pyrroloquinoline quinone, a chemotactic attractant for Escherichia coli [PDF]

Journal of Bacteriology, 1996
Escherichia coli is attracted by pyrroloquinoline quinone (PQQ), and chemotaxis toward glucose is enhanced by the presence of PQQ. A ptsI mutant showed no chemotactic response to either glucose or PQQ alone but did show a chemotactic response to a mixture of glucose and 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.
