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.
Other Notes
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
