A rooted phylogenetic tree showing the relationships between β-Ala
NMTase and other methyltransferases. The enzymes are BANMT, β-Ala
N-methyltransferase; DPOMT,
O-diphenol-O-methyltransferase; COMT, caffeic acid
O-methyltransferase; IEOMT, isoeugenol O-methyltransferase;
CAOMT, catechol O-methyltransferase; IMT, myo-inositol
O-methyltransferase; ILOMT, isoliquirifigenin
O-methyltransferase; CHOMT, chalcone O-methyltransferase;
SOMT, scoulerine-9-O-methyltransferase; MT; methyltransferase; and
HMCOMT, hydroxy N-methyl S-coclaurine
4-O-methyltransferase. The GenBank identification numbers are given
in Materials and Methods, and the species name is shown in brackets. The
bootstrap values above 60 are shown.
