Pyranose dehydrogenase (acceptor) ( EC 1.1.99.29, pyranose dehydrogenase, pyranose-quinone oxidoreductase, quinone-dependent pyranose dehydrogenase, PDH) is an enzyme with systematic name pyranose:acceptor oxidoreductase. [1] [2] [3] [4] [5] This enzyme catalyses the following chemical reaction
- (1) a pyranose + acceptor a pyranos-2-ulose (or a pyranos-3-ulose or a pyranos-2,3-diulose) + reduced acceptor
- (2) a pyranoside + acceptor a pyranosid-3-ulose (or a pyranosid-3,4-diulose) + reduced acceptor
This enzyme requires FAD. A number of aldoses and ketoses in pyranose form, as well as glycosides, gluco-oligosaccharides, sucrose and lactose can act as a donor.
