Identification and Quantification of PQQ

1989
PQQ can occur in free form, as a C5-addition compound, as a condensation product with amino acids (e.g. an oxazole) and in an extractable or covalently bound form. Free, underivatized PQQ can be quantified by several chromatographic methods and biological assays. However, alternative analytical procedures had to be developed for the other cases. The so-

Methanol Dehydrogenase, a PQQ-Containing Quinoprotein Dehydrogenase

2000
Methanol dehydrogenase (MDH; EC 1.1.99.8) catalyses the oxidation of methanol to formaldehyde in the periplasm of methylotrophic bacteria during growth on methanol or methane. It was first described in Methylobacterium extorquens (Anthony and Zatman, 1964a,b) and has subsequently been shown to be the one feature that is common to almost all ...

Copper-PQQ Interactions in Amine Oxidases

1989
Interactions between copper and PQQ in several amine oxidases have been probed by a variety of physical methods. A Cu(I)-semiquinone (PQQ●) state can be generated by substrate-reduction in the presence of ligands that stabilize Cu(I). This state has now been characterized in detail for amine oxidases from bovine plasma, porcine kidney, pea seedlings ...
