Pyrroloquinoline Quinone (PQQ) Labeling Moieties for the Sensitive Detection of Biomolecules. [PDF]

Since the development of the immunoassay, biomolecule detection via binding assays has become vitally important in many fields. High sensitivity in such assays usually requires low molecular weight labeling species (i.e., tracers) that typically must be

Pyrroloquinoline quinone (coenzyme PQQ) and the oxidation of SH residues in proteins

, 1993
PQQ catalyzes the oxidation of cysteamine, dithiothreitol(DTT), and reduced glutathione,respectively, at neutral pH. The time course of cysteamine oxidation was monitored by absorption spectroscopy using the 5,5\u27-dithiobis(2-nitrobenzoic acid) (DTNB ...

Development of a pyrroloquinoline quinone (PQQ) mediated glucose oxidase enzyme electrode for detection of glucose in fruit juice

, 1996
The electrochemistry of pyrroloquinoline quinone (PQQ) was examined and the coupling of PQQ with glucose oxidase was studied at different pH values. Optimal interaction between PQQ and glucose oxidase was observed at pH 3.5.

Reconstitution Study of sGDH with PQQ Adducts and Substrate and Product Analogs.

, 1999
Soluble glucose dehydrogenase (sGDH) is a homodimer that requires one pyrroloquinoline quinone (PQQ) and two Ca2+ cations per monomer subunit, to oxidize aldoses.
