Biochemical and Physiological Functions of Pyrroloquinoline Quinone

1991
Publisher Summary This chapter discusses the biochemical and physiological functions of pyrroloquinoline quinone (PQQ). Quinoproteins are distributed widely among prokaryotic and eukaryotic organisms. The prosthetic group of copper-containing amine oxidases from mammals, plants, and microorganisms have been identified as PQQ bound covalently to the ...

Pyrroloquinoline Quinone (PQQ) and Quinoprotein Enzymes

Antioxidants & Redox Signaling, 2001
This review summarises the characteristics, identification, and measurement of pyrroloquinoline quinone, the prosthetic group of bacterial quinoprotein dehydrogenases whose structures, mechanisms, and electron transport functions are described in detail. Type I alcohol dehydrogenase includes the "classic" methanol dehydrogenase; its x-ray structure and

Nutritional Essentiality of Pyrroloquinoline Quinone

1989
A chemically defined diet, based on synthetic amino acids, was fed to rats and mice. The control diet (+PQQ) was fortified with pyrroloquinoline quinone (PQQ) at 875 ug/kg. The deficient diet (-PQQ) contained no detectable PQQ. The -PQQ diet was fed to pregnant rats and, in later experiments, to mice throughout gestation. Newborn pups remained with the

Biochemistry: is pyrroloquinoline quinone a vitamin?

Nature, 2005
The announcement by Kasahara and Kato of pyrroloquinoline quinone (PQQ) as a 'new' vitamin has received considerable attention. We have since attempted to reproduce the findings on which their conclusion is based, namely that defects in lysine metabolism occur in PQQ-deprived rodents.
