Product Description: Vaccinia virus capping enzyme is a transcription initiation factor. Vaccinia virus capping enzyme is a heterodimer of D1 (844 aa) and D12 (287 aa) polypeptides that executes all three steps in m7GpppRNA synthesis. Vaccinia virus capping enzyme has been used widely as a reagent for capping and cap-labeling RNAs in vitro[1][2].
