Probably specifically methylates an O atom of its substrate. Does not seem to have metal cofactors; no metal ions were found via inductively coupled plasma atomic emission spectroscopy, and the residues that bind metal in homologs are not conserved. Homodimer. Was identified as a high-confidence drug target. Belongs to the class I-like SAM-binding methyltransferase superfamily. Cation-dependent O-methyltransferase family. It is not clear if Met-1 or Met-10 is the start codon. Truncated N-terminus.
