Substituted Quinoline Quinones as Surrogates for the PQQ Cofactor: An Electrochemical and Computational Study

, 2015
Pyrroloquinoline quinones (PQQ) are important cofactors that shuttle redox equivalents in diverse metalloproteins. Quinoline 7,8-quinones have been synthesized and characterized as surrogates for PQQ to elucidate redox energetics within metalloenzyme ...

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.

Investigation of the structure and mechanism of a PQQ biosynthetic pathway component, PqqC, and a bioinformatics analysis of potential PQQ producing organisms. [PDF]

, 2010
PQQ is an exogenous, tricyclic, quino-cofactor for a number of bacterial dehydrogenase reaction. It has also been proposed to play a role as a bacterial vitamin. The following work has defined 144 bacteria species that contain the machinery to form PQQ.
