Effects of pyrroloquinoline quinone and imidazole pyrroloquinoline on biological activities and neural functions

open access: yesHeliyon, 2020
Pyrroloquinoline quinone (PQQ) is contained in fruits and vegetables and in human breast milk. It has been reported that PQQ has high reactivity and changes to an imidazole structure (imidazole pyrroloquinoline) by a reaction with an amino acid at a high

The TonB dependent uptake of pyrroloquinoline-quinone (PQQ) and secretion of gluconate by Escherichia coli K-12

open access: yesbioRxiv, 2022
Glucose is taken up by Escherichia coli through the phosphotransferase system (PTS) as the preferred carbon source. PTS mutants grow with glucose as a carbon source only in the presence of pyrroloquinoline quinone (PQQ), which is needed as a redox ...

Pyrroloquinoline-Quinone Is More Than an Antioxidant: A Vitamin-like Accessory Factor Important in Health and Disease Prevention

open access: yesBiomolecules, 2021
Pyrroloquinoline quinone (PQQ) is associated with biological processes such as mitochondriogenesis, reproduction, growth, and aging. In addition, PQQ attenuates clinically relevant dysfunctions (e.g., those associated with ischemia, inflammation and ...

Discovery of a eukaryotic pyrroloquinoline quinone-dependent oxidoreductase belonging to a new auxiliary activity family in the database of carbohydrate-active enzymes. [PDF]

open access: yesPLoS ONE, 2014
Pyrroloquinoline quinone (PQQ) is a redox cofactor utilized by a number of prokaryotic dehydrogenases. Not all prokaryotic organisms are capable of synthesizing PQQ, even though it plays important roles in the growth and development of many organisms ...

Pyrroloquinoline Quinone Is an Effective Senomorphic Agent to Target the Pro-Inflammatory Phenotype of Senescent Cells. [PDF]

open access: yesAging Cell
As a natural senomorphic agent, PQQ targets the intracellular molecule. HSPA8 of senescent cells, resulting in significantly reduced expression of the SASP. PQQ holds prominent potential to delay chronological aging and ameliorate age‐related conditions by acting as an effective senomorphic agent.
