Could SARS-CoV-2 have artificial amino acids?

"Researchers have taken a technique that's been used a number of times before—engineering cells to use an artificial amino acid—and applied it to make a flu virus that acts as a vaccine. The vaccine is highly effective and, because it depends on an amino acid our cells don't use, it can't cause infections in us. Best yet, if the vaccine gets into cells with a normal flu virus, it interferes with its ability to generate an infection."

"In this new effort, the researchers took a new approach to creating a vaccine—modifying an influenza virus in such a way as disallow it from causing an infection in any patient.

The team started with the knowledge that viruses use certain amino acids as part of the infection process—they then modified an influenza virus by replacing one such amino acid with another that they had created in the lab—one that does not normally occur in viruses, or people. Without the right amino acid, the virus was still able to function, but it was unable to cause an infection—and because it was still a flu virus, its presence in the body caused the immune system to attack both them and any other type of flu virus encountered, thereby preventing an infection"

"Amino acids are the building blocks of proteins. As a rule, nature only uses 20 amino acids in all living organisms. "Using the possibilities opened up by synthetic biology, we have employed an additional artificial amino acid," reports researcher Carina A. Sommer.

"We have succeeded in incorporating a boric acid group, which exerts intrinsic affinity to sugar molecules, into the amino acid chain of a protein. In doing this, we have created an entirely new class of binding protein for sugar molecules," Sommer explains. This artificial sugar-binding function is superior to natural binding proteins (so-called lectins) both in strength and with regard to possible sugar specificities"

"Chinese researchers are said to have used coronaviruses in their work to develop an AIDS vaccine. HIV RNA fragments are believed to have been found in the SARS-CoV-2 genome."

"Nothing close to this combination has been found in nature. It is more likely to have been constructed in a laboratory through Gain-of-Function research."
