In enzymology, a pyranose oxidase (EC 1.1.3.10) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are D-glucose and O2, whereas its two products are 2-dehydro-D-glucose and H2O2.
Pyranose oxidase is able to oxidize D-xylose, L-sorbose, D-galactose, [1] and D-glucono-1,5-lactone, which have the same ring conformation and configuration at C-2, C-3 and C-4. [2]
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. The systematic name of this enzyme class is pyranose:oxygen 2-oxidoreductase. Other names in common use include glucose 2-oxidase, and pyranose-2-oxidase. This enzyme participates in pentose phosphate pathway. It employs one cofactor, FAD.
As of late 2007, 8 structures have been solved for this class of enzymes, with PDB accession codes 1TT0, 1TZL, 2F5V, 2F6C, 2IGK, 2IGM, 2IGN, and 2IGO.
Recently, pyranose oxidase has been gaining on popularity within biosensors. [1] Unlike glucose oxidase, it can produce higher power output, given that it is not glycosylated, has more favorable value of Michaelis-Menten constants, and can catalytically convert both anomers of glucose. It reacts with a wider range of substrates. Pyranose oxidase does not cause an unwanted pH shift. It is also possible to easily express and produce it in high yields using E. coli . [1]
Glyceraldehyde (glyceral) is a triose monosaccharide with chemical formula C3H6O3. It is the simplest of all common aldoses. It is a sweet, colorless, crystalline solid that is an intermediate compound in carbohydrate metabolism. The word comes from combining glycerol and aldehyde, as glyceraldehyde is glycerol with one alcohol group oxidized to an aldehyde.
