Procedure

Chemicals. Caffeine, theophylline, theobromine, paraxanthine, 7-methylxanthine, 3-methylxanthine, xanthine, ammonium acetate, acetic acid, 2,4-pentanedione, spinach ferredoxin reductase, and spinach ferredoxin were purchased from Sigma-Aldrich. Reductase and ferredoxin of Pseudomonas sp. 9816 naphthalene dioxygenase were kindly provided by Dr. David T. Gibson. Soytone was obtained from Becton, Dickinson and Company. High-pressure liquid chromatography (HPLC)-grade methanol (J. T. Baker) was used in chromatographic studies.
