Researchers at Oak Ridge National Laboratory, the University of Tennessee at Chattanooga, and Tuskegee University used mathematics to predict which regions of the SARS-CoV-2 spike protein are most likely to mutate.

In a study published in Polymersthe team analyzed topology from more than 13,000 protein data bank structures and found that mutations in the viral spike protein are likely to occur in regions of high topological free energy, making the protein less stable.

The omicron variant of SARS-CoV-2 mutated in the region that corresponds to the researchers’ calculations, which confirms the results of the article.

This methodology allows scientists to predict where protein mutations may occur using mathematics and can be applied to any protein, potentially opening the door to a better understanding of viral dynamics and more effective drug therapy.

“We think this approach is virus-independent,” said ORNL’s Bobby Sumpter. “It’s all based on protein topology.”
