Faustovirus Capping Enzyme (S17)
Faustovirus Capping Enzyme (S17) generates 7-methylguanylate cap (Cap-0) structures to the 5′ ends of uncapped RNA, which is essential for efficient translation of in vitro-transcribed RNA in eukaryotic expression systems. RNA transcripts can be capped in less than one hour in the presence of the capping enzyme, reaction buffer, GTP, and a methyl donor. Compared to Vaccinia Capping Enzyme (Cat. # 2460A/B), Faustovirus Capping Enzyme exhibits high enzyme activity over a broader temperature range, making it suitable for various 5′ sequences.
The use of the Faustovirus Capping Enzyme (S17) in the same reaction with mRNA Cap 2′-O-Methyltransferase (Cat. # 2470A/B) generates Cap-1 RNA, which reduces the innate immune response to in vitro-transcribed RNA when used in vivo.

Overview
- Generates 7-methylguanylate cap structures (Cap-0) to the 5′ ends of uncapped RNA
- Can be used together with mRNA Cap 2′-O-Methyltransferase (Cat. # 2470A/B) to generate Cap-1 RNA
- Exhibits enzymatic activity over a broader temperature range compared to Vaccinia Capping Enzyme
Obtain enzymatic activity over a broader temperature range
Capping reactions were performed using Faustovirus Capping Enzyme (S17) (FCE; Cat. # 2480A) or Vaccinia Capping Enzyme (VCE; Cat. # 2460A) at various reaction temperatures. The capping efficiency (% Cap-0 RNA) was measured by LC-MS. FCE demonstrated increased capping efficiency over a broader temperature range than VCE.
