Another type of sensor was based on the utilization of glucose dehydrogenase enzyme coupling with /ra(2,2 -bipyridylruthenium(II) complex [31]. This sensor can be used in the 10-2500-pmol/L concentration range. Several interferences occur, like NADH, oxalate, proline, and tripropylamine. However, gluconic acid and NAD+ do not interfere.

This enzyme [EC 1.1.1.126], also known as 2-keto-3-deoxy-D-gluconate dehydrogenase, catalyzes the reaction of 2-dehydro-3-deoxy-D-gluconate with NADP to produce (45,55 )-4,5-dihydroxy-2,6-dioxohexanoate and NADPH.

Figure 6. 51V NMR spectra of 0.5, 1.0, and 5.0 mM total vanadate in 150 mM imidazole at pH 8.0. The V2 (—555 ppm) and V4 (—579 ppm) resonances are indicated by arrows. The V2 resonance (—573 ppm) is upfield of the Vj and downfield of the V4 resonance, and the V5 resonance (—585 ppm) is furthest upfield. The H+-dependent equilibrium constants K12 and K14 are defined, and plots of [V2] as a function of [ V2]2 and [V4] as a function of [V2]4 are shown for a study carried out at constant ionic strength. The data shown in these plots were reported previously as assay conditions for studies of 6-phospho gluconate dehydrogenase from sheep liver (Data are from reference 35).
