| Reactant | Caffeine | HCID 2519 | — |
| Reactant | 1,3-dimethyl-7-propyl-2,3,6,7-tetrahydro-1H-purine-2,6-dione | HCID 847168 | — |
| Product | Theobromine | HCID 5429 | — |

Reaction Steps
The 1,3-methyl-7-alkylxanthine was thus converted to the corresponding 3-methyl-7-alkylxanthine. The results of the conversion reaction are shown in FIG. 2. It is seen that in using either of the substrates (caffeine or 1,3-dimethyl-7-propylxanthine) the transformant strain having pCA32A, i.e., P. putida IF-3-9C-21/pCA32A, produces the corresponding conversion product (theobromine or 3-methyl-7-propylxanthine, respectively) in an amount about 2 to 4 times that produced by P. putida IF-3-9C-21.
