Alignment of β-Ala NMTase deduced amino acid sequence with sequences
of other well-characterized O-methyltransferases from alfalfa
(Medicago sativa). The sequences are identified by their GenBank
identification numbers. COMT, Caffeic acid 3-O-methyltransferase;
CHOMT, chalcone O-methyltransferase; IFOMT, isoflavone
O-methyltransferase; and BAMT, β-Ala NMTase. Conserved residues
are marked by an asterisk, and conserved substitutions are marked by one or
two dots.
