ENZYME entry: EC 2.1.1.160

Accepted Name
caffeine synthase
Alternative Name(s)
3N-methyltransferase
dimethylxanthine methyltransferase
Reaction catalysed
  • S-adenosyl-L-methionine + theobromine <=> caffeine + H(+) + S-adenosyl-L-homocysteine
  • 1,7-dimethylxanthine + S-adenosyl-L-methionine <=> caffeine + H(+) + S-adenosyl-L-homocysteine
  • 7-methylxanthine + S-adenosyl-L-methionine <=> H(+) + S-adenosyl-L-homocysteine + theobromine
Comment(s)
Paraxanthine is the best substrate for this enzyme but the paraxanthine pathway is considered to be a minor pathway for caffeine biosynthesis.
