Journal of Animal Science and Biotechnology, 2021 Background Oxidative stress is a main cause of piglet gut damage and diarrhea. Pyrroloquinoline quinone (PQQ), is a novel redox cofactor with antioxidant properties. However, the effect and mechanism that PQQ supplementation decreases oxidative injury in

PQQ Supplementation and SARS-CoV-2 Spike Protein-Induced Heart Inflammation
Natural Product Communications, 2022 SARS-CoV-2 spike protein-induced heart inflammation may originate from either COVID-19 infection or the administration of COVID-19 mRNA vaccines. As pyrroloquinoline quinone (PQQ) is a scavenger of free radicals, redox cofactor, and antioxidant which ...

Pyrroloquinoline quinone (PQQ) inhibits lipopolysaccharide induced inflammation in part via downregulated NF-κB and p38/JNK activation in microglial and attenuates microglia activation in lipopolysaccharide treatment mice. [PDF]
PLoS ONE, 2014 Therapeutic strategies designed to inhibit the activation of microglia may lead to significant advancement in the treatment of most neurodegenerative diseases.

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.

Cloning of Klebsiella pneumoniae pqq genes and PQQ biosynthesis in Escherichia coli [PDF]
FEMS Microbiology Letters, 1990 We have cloned genes from Klebsiella pneumoniae which are required for pyrroloquinoline quinone (PQQ) biosynthesis. The cloned 6.7 kb fragment can complement several chromosomal pqq mutants. Escherichia coli strains are unable to synthesize PQQ but E. coli strains containing the cloned 6.7 kb K.
