Pyrroloquinoline Quinone PQQ dependent Glucose Dehydrogenase

The reduced cofactor can be reoxidised by two one-electron-transfers, for example the common oxidant ubiquinone. [Pg.674]

An alternative biosensor system has been developed by Hart et al. [44] which involves the use of the NAD+-dependent GDH enzyme. The first step of the reaction scheme involves the enzymatic reduction of NAD+ to NADH, which is bought about by the action of GDH on glucose. The analytical signal arises from the electrocatalytic oxidation of NADH back to NAD+ in the presence of the electrocatalyst Meldola s Blue (MB), at a potential of only 0Y. Biosensors utilising this mediator have been reviewed elsewhere [1,17]. Razumiene et al. [45] employed a similar system using both GDH and alcohol dehydrogenase with the cofactor pyrroloquinoline quinone (PQQ), the oxidation of which was mediated by a ferrocene derivative. [Pg.503]

The other less common type of phenol biosensor involves enzymes like PQQ (pyrroloquinoline quinone)-dependent glucose dehydrogenase (GDH) (9-12) or... [Pg.114]
