ID   1.1.3.50
DE   C-glycoside oxidase.
CA   carminate + O2 = 3'-dehydrocarminate + H2O2.
CC   -!- A flavoprotein (FAD).
CC   -!- This bacterial enzyme participates in degradation of certain
CC       C-glucosides by catalyzing the oxidation of the hydroxyl group at
CC       position 3 of the glycose moiety.
CC   -!- The enzyme was found active with assorted C-glycosides, such as
CC       carminate, mangiferin, and C(6)-glycosylated flavonoids, but not with
CC       D-glucose or C(8)-glycosylated flavonoids.
