Study shows how AFV3-109 protein with slipknot structure folds and unfolds based on temperature

Scientists from the Pacific Quantum Center of Far Eastern Federal University (FEFU) figured out how the AFV3-109 protein with slipknot structure folds and unfolds depending on temperature. The protein is typical for the viruses of the oldest single-celled organisms that can survive in the extreme conditions of underwater volcanic sources - archaea. The research outcome appears in PLOS ONE.

Vibrational motions of spike proteins correlate with infectivity, lethality of SARS-CoV-2 virus

When someone struggles to open a lock with a key that doesn't quite seem to work, sometimes jiggling the key a bit will help. Now, new research from MIT suggests that coronaviruses, including the one that causes Covid-19, may use a similar method to trick cells into letting the viruses inside.
