New Structures of SARS-CoV-2 Lead to Improved Understanding of Viral Replication Engine

New Structures of SARS-CoV-2 Lead to Improved Understanding of Viral Replication Engine:  Researchers conducting experiments at the U.S. Department of Energy’s Advanced Photon Source make significant strides in understanding the structures, active sites, and reactivity of SARS-CoV-2, which may lead to a better understanding of why SARS-CoV-2 is much more transmittable in comparison to other coronaviruses like SARS-CoV and MERS-CoV.
