A more robust spike protein could be the secret to the ability of newer COVID-19 variants to spread faster than the original strain, according to a new study.
Led by Professor Bing Chen, professor of pediatrics at Boston Children’s Hospital, the study looked at changes in peak proteins belonging to the D614G mutation, which is achieved by the Brazilian variants of South Africa and the United Kingdom. .
All of these variations are known to spread more easily compared to the original strain.
“Let’s say the original virus has 100 peaks,” Chen explained in a press release. “Due to the instability of the shape, you can have only 50 percent of them functional. In the G614 variants, you can have 90% that are functional, so even if they don’t bond as well, the chances are greater that you have an infection. “
