Glossary: |
carminate = 7-(β-D-glucopyranosyl)-3,5,6,8-tetrahydroxy-1-methyl-9,10-dioxo-9,10-dihydroanthracene-2-carboxylate |
Other name(s): |
carA (gene name) |
Systematic name: |
carminate:oxygen 3′-oxidoreductase (H2O2-forming) |
Comments: |
A flavoprotein (FAD). This bacterial enzyme participates in degradation of certain C-glucosides by catalysing the oxidation of the hydroxyl group at position 3 of the glycose moiety. The enzyme was found active with assorted C-glycosides, such as carminate, mangiferin, and C6-glycosylated flavonoids, but not with D-glucose or C8-glycosylated flavonoids. |
