Accepted name: caffeine dehydrogenase
Reaction: caffeine + ubiquinone + H2O = 1,3,7-trimethylurate + ubiquinol
Glossary: caffeine = 1,3,7-trimethylxanthine
Systematic name: caffeine:ubiquinone oxidoreductase
Comments: This enzyme, characterized from the soil bacterium Pseudomonas sp. CBB1, catalyses the incorporation of an oxygen atom originating from a water molecule into position C-8 of caffeine. It can also use theobromine as substrate. The enzyme utilizes short-tail ubiquinones as the preferred electron acceptor.
