The conserved signature motifs of class II OMT in CsOMTs, SlOMT3, AtCOMT, and ObFOMT5. The amino acid sequences of CsOMTs were aligned with those of class II OMT SlOMT3, AtCOMT, and ObFOMT5 using Clustal-W. The SAM binding motifs and the COMT motifs were indicated under the aligned sequences with their consensus sequences (X indicates any amino acid). Red triangles indicate the catalytic residues of class II OMT. Identical and similar amino acids are shaded in black and grey, respectively
