2-O-Methyl Transferase  

High Quality & Purity Enzyme manufactured from Recombinant source

Recombinant 2-O-Methyl Transferase from Vaccinia virus is produced in Escherichia coli. It catalyzes the addition of a methyl group at the 2′-O position of the first nucleotide adjacent to the cap structure at the 5′ end of the RNA. The enzyme utilizes SAM as a methyl donor to methylate capped RNA (Cap 0) resulting in a cap-1 structure.
