Type: | Family | Name: | SAM dependent carboxyl methyltransferase |
Description: | This family of plant methyltransferases contains enzymes that act on a variety of substrates including salicylic acid, jasmonic acid and 7-Methylxanthine. Caffeine is synthesized through sequential three-step methylation of xanthine derivatives at positions 7-N, 3-N, and 1-N. The protein 7-methylxanthine methyltransferase (designated as CaMXMT) catalyses the second step to produce theobromine []. | Short Name: | MeTrfase_7 |
