DE   theobromine synthase.
AN   monomethylxanthine methyltransferase.
AN   MXMT.
CA   7-methylxanthine + S-adenosyl-L-methionine = H(+) + S-adenosyl-L-
CA   homocysteine + theobromine.
CC   -!- Can also catalyze the conversion of paraxanthine into caffeine,
CC       although the paraxanthine pathway is considered to be a minor pathway
CC       for caffeine biosynthesis.
CC   -!- This is the third enzyme in the caffeine biosynthesis pathway.
