Caffeine synthase
Definition:
EC Tree > 2 Transferases > 2.1 Transferring one-carbon groups > 2.1.1 Methyltransferases > 2.1.1.160 caffeine synthase
Caffeine synthase methylates 1,7-dimethylxanthine (paraxanthine, best substrate), 3,7-dimethylxanthine (theobromine) and even 7-methylxanthine into 1,3,7-trimethylxanthine (caffeine), completing caffeine biosynthesis in tea and coffee plants.
