Product Description
Vaccinia virus capping enzyme is derived from a recombinant E. coli strain carries the genes for the Vaccinia capping enzyme. This single enzyme is composed of two subunits (D1 and D12) and has three enzymatic activities (RNA triphosphatase and guanylyltransferase by the D1 subunit and guanine methyltransferase by the D12 subunit). Vaccinia virus Capping Enzyme is effective to catalyze the formation of cap structure, which can specifically attach the 7-methylguanylate cap structure (m7Gppp, Cap 0) to the 5' end of RNA. Cap structure (Cap 0) plays an important role in mRNA stabilization, transport and translation in eukaryotes. Capping RNA by enzymatic reaction is an effective and simple method which can significantly improve the stability and translation of RNA for in vitro transcription, transfection, and microinjection.
