Ion mobility studies of Pyrroloquinoline Quinone Aza-Crown Ether-Lanthanide Complexes [PDF]
, 2022 Lanthanide-dependent enzymes and their biomimetic complexes have arisen as an interesting target of research in the last decade. These enzymes, specifically, pyrroloquinoline quinone (PQQ)-bearing methanol dehydrogenases, efficiently turn over alcohols ...

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%.

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

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 ...

Escherichia coli is unable to produce pyrroloquinoline quinone (PQQ) [PDF]
Microbiology, 1997 Many bacteria can synthesize the cofactor pyrroloquinoline quinone (PQQ), a cofactor of several dehydrogenases, including glucose dehydrogenase (GCD). Among the enteric bacteria, Klebsiella pneumoniae has been shown to contain the genes required for PQQ biosynthesis.

Crystal structure of a calcium(II)-pyrroloquinoline quinone (PQQ) complex outside a protein environment. [PDF]
Acta Crystallogr C Struct Chem, 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;

Pyrroloquinoline quinone (PQQ) is the organic cofactor in soybean lipoxygenase‐1 [PDF]
FEBS Letters, 1988 Treatment of soybean lipoxygenase‐1 (SLO) with phenylhydrazine (PH) induced inactivation and a maximum (350 nm) in the absorption spectrum of the enzyme. To detach the product having this absorption maximum, proteolysis was required. The product appeared to be the C(5) phenylhydrazone of pyrroloquinoline quinone (PQQ).
