Fig. 1 in Molecular and biochemical characterization of caffeine synthase and purine alkaloid concentration in guarana fruit
Fig. 1. Main metabolic pathway for the biosynthesis and biodegradation of caffeine. SAM = S-adenosyl-L-methionine, SAH = S-adenosyl-L-homo-cysteine. I = 7-methylxanthosine synthase (xanthosine methyltransferase), II = nucleosidase, III = theobromine synthase or caffeine synthase, IV = caffeine synthase.
