Biosynthesis of caffeine underlying the diversity of motif B' methyltransferase.

Natural product communications - 1 May 2015

Nakayama Fumiyo, Mizuno Kouichi, Kato Misako

Abstract excerpt

Caffeine (1,3,7-trimethylxanthine) and theobromine (3,7-dimethylxanthine) are well-known purine alkaloids in Camellia, Coffea, Cola, Paullinia, Ilex, and Theobroma spp. The caffeine biosynthetic pathway depends on the substrate specificity of N-methyltransferases, which are members of the motif B' methyl-transferase family. The caffeine biosynthetic pathways in purine alkaloid-containing plants might have evolved...
