The Natural Redox Cofactor Pyrroloquinoline Quinone (PQQ) Enables Photocatalytic Radical Cyclizations. [PDF]
Angew Chem Int Ed EnglNatural alcohol and sugar dehydrogenases that utilize the redox cofactor pyrroloquinoline quinone (PQQ) can be repurposed for enantioselective photoredox catalysis. Upon blue‐light irradiation, redox‐neutral radical cyclizations are catalyzed. This work adds a new class of enzymes to the toolbox of photobiocatalysis.

Endophytic Biostimulant Pyrroloquinoline Quinone Enhances Banana Growth and Primes Immunity Against Fusarium Wilt. [PDF]
Physiol PlantABSTRACT Pyrroloquinoline quinone (PQQ) is a redox cofactor derived from prokaryotes that participates in various biological processes involving dehydrogenase enzymes. Previous field trials identified a PQQ‐producing endophyte, Burkholderia seminalis 869T2, which enhances banana growth and reduces Fusarium wilt incidence from 24.5% to 3.4%.

Environmental Enrofloxacin Exposure as a Modifiable Driver of Mitochondria-Mediated Intestinal Aging and Barrier Dysfunction. [PDF]
Aging CellEnvironmentally relevant enrofloxacin accelerates intestinal aging by impairing epithelial mitochondrial function, disrupting barrier integrity, and reshaping the gut microbiota. Mitochondrial restoration with pyrroloquinoline quinone alleviates hypoxia, inflammation, and gut damage.
