SARS-CoV-2 spike protein binds to human cells 1,000 times tighter than closest bat relative coronavirus RaTG13, research demonstrates
Newsweek (7/10, Osborne) reported, “The new coronavirus appears to bind to human cells about 1,000 times tighter than its closest bat relative, researchers have found.” In a recent study, researchers “analyzed the spike protein of SARS-CoV-2 and compared it with the closest relative of the virus, a bat coronavirus called RaTG13,” and found “the spike protein of the new coronavirus is much more stable than that of RaTG13,” which “makes it able to bind to human cells around 1,000 more tightly than the bat coronavirus.” The study was published in Nature Structural & Molecular Biology.
