Supercomputers Accelerate COVID-19 Research, vaccine Efforts
The COVID-19 pandemic spurred scientists to harness supercomputing power to understand the SARS-CoV-2 virus and develop treatments.supercomputers, which use artificial intelligence and machine learning to process vast amounts of data, are now essential tools in studying the virus and planning for future outbreaks.
Researchers have focused on the coronavirus spike protein, which facilitates the virusS entry into human cells. Neutralizing this protein is a key target for COVID-19 vaccines and therapeutics. However, simulating the spike protein’s various forms and interactions with molecules requires immense computational power.
Ahmet Yildiz,a professor at the University of California,Berkeley,and Mert Gur at Istanbul Technical University are using supercomputing at the Texas Advanced Computing center (TACC) to study the spike protein’s movements. They combine molecular dynamics simulations with single-molecule experiments to uncover the virus’s secrets.
Yildiz and Gur are studying the process by which the spike protein binds to human cells and inserts RNA. Their research, published in the Journal of Chemical Physics, identifies three critical phases. First, the spike protein changes from a closed to an open configuration. Second, it binds to a receptor on the cell’s surface, triggering a change within the protein. a newly exposed surface interacts with the cell membrane, allowing viral RNA to enter.
Electron microscope images revealed the structure of the spike protein, but only showed stable configurations.Computer modeling is needed to understand the transitional steps between these configurations.
Yildiz said the microscope images provided a starting point to create models of every atom in the protein and its habitat. They then set the protein in motion using supercomputers to observe what happened.
They showed that the S protein visits an intermediate state before it can dock to the receptor protein on the host cell membrane and this intermediate state can be useful for drug targeting to prevent the S protein to initiate viral infection.
Simulating these interactions at the atomic level is computationally intensive. Yildiz and Gur were granted time on the Stampede2 supercomputer at TACC through the COVID-19 HPC Consortium. Simulating one microsecond of the virus interacting with human cells takes weeks on a supercomputer.
Gur and his collaborators have been re-enacting the atomic movements of the spike protein as it interacts with ACE2 receptors, which line the surface of many cell types. The researchers found that the spike protein visits an intermediate state before docking to the receptor protein, which could be a useful target for drugs.
What’s next
Scientists anticipate relying on computational models to forecast future influenza viruses. Supercomputers will be needed to track virus structures, mutations, and design appropriate vaccines. Advanced AI and ML will further enhance supercomputer capabilities to predict and prevent future pandemics, potentially saving millions of lives.
