SARS RNA Synthesis and Processing Activities – SARS-RNA-SPA
We deciphered regulation mechanisms of the polymerase activity in the replication / transcription complex and we have identified a proofreading mechanism unique in RNA virus world. In addition, we characterize the viral enzymes involved in the synthesis of the cap structure present at the 5 ' end of mRNA. This structure is needed to translate RNA into viral proteins and limit their recognition by innate immunity mechanisms.
