Pyrroroquinoline Quinone (PQQ) Improves the Quality of Holstein Bull Semen during Cryopreservation

Animals
Cryopreserved semen is extensively utilized in the artificial insemination (AI) of domestic animals; however, suboptimal conception rates due to oxidative damage following AI continue to pose a challenge.

Tn5-directed cloning of pqq genes from Pseudomonas fluorescens CHA0: mutational inactivation of the genes results in overproduction of the antibiotic pyoluteorin.

, 1995
Pseudomonas fluorescens CHA0 produces several secondary metabolites, e.g., the antibiotics pyoluteorin (Plt) and 2,4-diacetylphloroglucinol (Phl), which are important for the suppression of root diseases caused by soil-borne fungal pathogens.

Reconstitution Study of sGDH with PQQ Adducts and Substrate and Product Analogs.

, 1999
Soluble glucose dehydrogenase (sGDH) is a homodimer that requires one pyrroloquinoline quinone (PQQ) and two Ca2+ cations per monomer subunit, to oxidize aldoses.

Pyrroloquinoline quinone promotes human mesenchymal stem cell-derived mitochondria to improve premature ovarian insufficiency in mice through the SIRT1/ATM/p53 pathway

Stem Cell Research & Therapy
Background DNA damage and oxidative stress induced by chemotherapy are important factors in the onset of premature ovarian insufficiency (POI). Studies have shown that mitochondria derived from mesenchymal stem cells (MSC-Mito) are beneficial for age ...

The Effects of Illumination onthe Oxidation Reactions of PQQ. Lousine Boyadzhyan & Alicia McCarthy

, 1999
PQQ, formally known as 2,7,9-tricarboxy-1H-pyrrolo [2,3-f] quinoline-4,5-dione, exists as an enzyme cofactor in bacterial methanol and glucose dehydrogenases. Since its discovery in 1979, the reactivity of PQQ has attracted much research attention.

Synthesis of PQQ Adducts andReconstitution Studies with sGDH.

, 2000
Soluble glucose dehydrogenase (sGDH) is a homodimeric quinoprotein found in Acinetobacter calcoaceticus , that effectively catalyzes the oxidation of aldose sugars to their corresponding aldonolactones, for example, glucose to gluconolactone.
