General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in biofuel cell research. For more information see the article in biofiles.

Application

Glucose dehydrogenase from Pseudomonas sp. has been used for the oxidation of glucose as a part of flow-injection analysis detection. It has also been used to regenerate the consumed nicotinamide adenine dinucleotide (NADH) during the removal of pyruvate by lactate dehydrogenase.

Biochem/physiol Actions

In bacteria, the membrane integrated glucose dehydrogenase catalyses the conversion of glucose to gluconic acid. It uses pyrroloquinoline quinone as a coenzyme. The intracellular glucose dehydrogenase lack this cofactor. It is a nicotinamide adenine dinucleotide (NADH) dependent enzyme.

Unit Definition

One unit corresponds to the amount of enzyme which will oxidizes 1 μmole β-D-glucose to D-glucono-δ-lactone per minute at pH 8.0 and 37 °C

A new extracellular flavin adenine dinucleotide (FAD)-dependent glucose dehydrogenase from Glomerella cingulata (GcGDH) was electrochemically studied as a recognition element in glucose biosensors. The redox enzyme was recombinantly produced in Pichia pastoris and homogeneously purified, and its glucose-oxidizing properties on

Here we report on the complete genome sequence of Cupriavidus basilensis OR16 NCAIM BO2487. The genome of strain OR16 contains 7,534 putative coding sequences, including a large set of xenobiotics-degrading genes and a unique glucose dehydrogenase gene that is absent

An excellent electrochemical sensing platform has been designed by combining the huge specific surface area of carbon nanotubes (CNTs) and the remarkable conductivity of ionic liquid (IL). IL can easily untangle CNTs bundles and disperse CNTs by itself under grinding

A glucose bio-battery prototype independent of oxygen is proposed based on a glucose dehydrogenase (GDH) bioanode and a graphite cathode with an iodide/tri-iodide redox couple. At the bioanode, a NADH electrocatalyst, poly(methylene blue) (PMB), which can be easily grown on

A concept for a tear glucose sensor based on amperometric measurement of enzymatic oxidation of glucose was previously presented, using glucose dehydrogenase flavin adenine dinucleotide (GDH-FAD) as the enzyme. Glucose dehydrogenase flavin adenine dinucleotide is further characterized in this article
