ENZYME entry: EC 2.1.1.160
| Accepted Name |
|---|
| Caffeine synthase.
|
| Alternative Name(s) |
|---|
| 3N-methyltransferase. |
| Dimethylxanthine methyltransferase. |
| Reaction catalysed |
|---|
- S-adenosyl-L-methionine + 3,7-dimethylxanthine <=> S-adenosyl-L-homocysteine + 1,3,7-trimethylxanthine
- S-adenosyl-L-methionine + 1,7-dimethylxanthine <=> S-adenosyl-L-homocysteine + 1,3,7-trimethylxanthine
- S-adenosyl-L-methionine + 7-methylxanthine <=> S-adenosyl-L-homocysteine + 3,7-dimethylxanthine
|
| Comment(s) |
|---|
| Paraxanthine is the best substrate for this enzyme but the
paraxanthine pathway is considered to be a minor pathway for caffeine
biosynthesis.
