Design Notes

The A27L protein is a crucial viral protein that plays essential roles in virus attachment, membrane fusion, intracellular transport of the virus within the host cell, and the formation of enveloped virion particles. The protein encoded by the A27L gene is necessary for the cell-to-cell transmission of viral particles. Deleting the A27L gene significantly impairs the virus's ability to spread between cells, resulting in substantially reduced plaque size. Therefore, we chose the A27L protein as the target for our experiments. Without an artificial translation system, the modified virus cannot synthesize complete A27L, leading to a drastic reduction in EEV formation, which greatly decreases the infectiousness and pathogenicity of the modified virus. Viruses unable to synthesize complete A27L mostly remain at the IMV stage, unable to spread over long distances, thereby ensuring the safety of the experiment and its applications. Only when an artificial translation system and unnatural amino acids are added can the modified virus synthesize complete A27L.
