Following Glucose Oxidase Activity by Chemiluminescence and Chemiluminescence Resonance Energy Transfer (CRET) Processes Involving Enzyme-DNAzyme Conjugates

open access: yesSensors, 2011
A hybrid consisting of glucose oxidase-functionalized with hemin/G-quadruplex units is used for the chemiluminescence detection of glucose. The glucose oxidase-mediated oxidation of glucose yields gluconic acid and H2O2.

Engineering Galactose Oxidase to Increase Expression Level in E. coli, Enhance Thermostability and Introduce Novel Activities [PDF]

open access: yes, 2003
For the first time, we functionally expressed the fungal glycosylated copper-containing enzyme, galactose oxidase, in Escherichia coli. The generation of fully functional GOase confirms that the formation of the unusual thioether bond is an auto ...

The Oxidation of 1-Deuterated Glucose by Glucose Oxidase

open access: yesJournal of Biological Chemistry, 1967
Abstract In order to trace the pathway of substrate-derived hydrogen in the mechanism of the glucose oxidase reaction, the kinetics of oxidation of d-glucose-1-2H was studied by conventional and stopped flow spectrophotometric methods. The results were compared with those for d-glucose-1-1H.
