CD Definition:
SAM dependent carboxyl methyltransferase; 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.
