Description

The vaccinia virus capping system uses vaccinia virus capping enzyme and other components to add a 7-methylguanosine cap structure (Cap 0) to the 5´ end of RNA. In eukaryotes, the 7-methylguanosine cap structure affects mRNA stability, transport, and translation. Enzymatically capping RNA is a simple and effective method to enhance the stability and translation of RNA used in in vitro transcription, transfection, and microinjection. Additionally, labeled GTP used in the reaction provides a convenient labeling method for any RNA with a 5´ triphosphate end.

The vaccinia virus capping enzyme consists of two subunits (D1 and D12). The D1 subunit, which is the mRNA-capping enzyme catalytic subunit, has RNA triphosphatase, guanylyltransferase, and guanine methyltransferase activities. The D12 subunit, which is the mRNA-capping enzyme regulatory subunit, regulates the capping activity of the D1 subunit. These activities are necessary to add a complete Cap 0 structure, i.e., m7Gppp(5´)N. The capping reaction is not only highly efficient, achieving up to 100%, but also ensures correct orientation, unlike co-transcriptional capping which may add some cap analogs.

Our DNA-Free enzymes are all recombinant proteins and purified through multiple steps, devoid of genomic and plasmid DNA from the production strain.

Unit Definition
