Importantly, this has actually highlighted the basic concerns about poxviruses that have actually stayed unanswered to this day.One such essential question lies, rather actually, at the core of the matter: “We know that for poxviruses to be infective, their viral core needs to be appropriately formed. “Previous experiments in virology, biochemistry, and genetics recommended numerous core protein candidates for poxviruses, however there were no experimentally-derived structures available,” states ISTA PhD trainee Julia Datler, one of the co-first authors of the study.Thus, the group begun by computationally predicting designs of the primary core protein candidates, utilizing the now-famous AI-based molecular modeling tool AlphaFold.In parallel, Datler was setting the tasks biochemical and structural foundations by drawing on her background in virology and the Schur groups main know-how: cryogenic electron microscopy, or cryo-EM for short.Cryo-electron tomogram of an entire Vaccinia infection.
