Thermostable chimeric PQQ glucose dehydrogenase [PDF]

FEBS Letters, 1995
The thermal stability of PQQ glucose dehydrogenases (PQQGDHs) which were chimeras with more than 95% made up of the N‐terminal region of Escherichia coli PQQGDH and the rest made up of the C‐terminal region of Acinetobacter calcoaceticus PQQGDHswas investigated. Among the chimeric PQQGDHs, E97A3 (E. coli 97% and A.

Pre-conditioning with PQQ during pregnancy alleviates LPS-induced placental damage and improves the fetal survival and growth in mice

Frontiers in Endocrinology
BackgroundIntrauterine infection is a major cause of preterm birth, fetal demise, and growth restriction. Placental damage resulting from such infections plays a central role in mediating these adverse outcomes.

Enzymatic Electrosynthesis for Sustainable CO2 Conversion: Advancing Circular Carbon Economy

Carbon Energy, Volume 8, Issue 10, October 2026.
Enzymatic electrosynthesis (EES) offers molecular precision in synthesizing value‐added products from CO2. We highlight its distinct edge over alternative enzyme‐hybrid systems and analyze electron transfer pathways. Key strategies to overcome electron transfer bottlenecks and expand product diversity are addressed, and also data‐driven approaches for ...

Radiotherapy‐Induced Side Effects: Epidemiology, Pathogenesis, Prevention and Treatments

MedComm, Volume 7, Issue 10, October 2026.
Radiotherapy for malignancies frequently injures the organs’ systems through oxidative stress, fibrosis, inflammation, and vascular damage. This review systematically maps the epidemiology, pathogenesis, and emerging therapies to propose a mechanism‑network‑targeted framework for integrated, personalized care in radiation oncology.

The Structure of a Biosynthetic Intermediate of Pyrroloquinoline Quinone (PQQ) and Elucidation of the Final Step of PQQ Biosynthesis

, 2016
Pyrroloquinoline quinone (PQQ) is a tricyclic o-quinone, which serves as a cofactor in several enzyme-catalyzed redox reactions in certain bacteria. PQQ is also important for human health, and its role as a vitamin in mammals has recently been suggested.

Crystal structure of a calcium(II)–pyrrolo­quinoline quinone (PQQ) complex outside a protein environment1 [PDF]

, 2020
Pyrroloquinoline quinone (PQQ) is an important cofactor of calcium‐ and lanthanide‐dependent alcohol dehydrogenases, and has been known for over 30 years. Crystal structures of Ca–MDH enzymes (MDH is methanol dehydrogenase) have been known for some time;

Deciphering the assembly process of PQQ dependent methanol dehydrogenase

Nature Communications
Pyrroloquinoline quinone (PQQ)-dependent methanol dehydrogenases (MDHs), the periplasmic metalloenzymes in Gram-negative methylotrophic bacteria, play a pivotal role in methane and methanol bio-utilization.
