	GO:0008170	N-methyltransferase activity	PMID:12746542	ECO:0000314			F		Based on methods: three types of cDNAs encoding N-methyltransferases were isolated from immature fruits of coffee (Coffea arabica) plants, and designated as CaXMT1, CaMXMT2, and CaDXMT1, respectively. The bacterially expressed encoded proteins were characterized for their catalytic properties. Using these recombinant proteins, catalytic specificity was determined with the following substrates: XMP, xanthosine, xanthine, 1-methylxanthine, 3-methylxanthine, 7-methylxanthine, paraxanthine, theobromine, and theophylline (Fig. ​(Fig.3B–D;3B–D; Table ​TableI).I). Purified CaXMT1 solely catalyzed conversion of xanthosine to 7-methylxanthosine	complete CACAO 4251
