Abstract

Strong under pressure Human cytomegalovirus (HCMV) is a member of the herpesvirus family that can cause life-threatening infections in those who are immunocompromised. HCMV encodes a genome that is about 50% larger than that of herpes simplex virus 1 (the virus that causes cold sores), but these two viruses have similar-sized capsids. Yu et al. used cryo–electron microscopy to determine the structure of the HCMV capsid to 3.9-Å resolution. This is the first high-resolution capsid structure from the herpesvirus family. It reveals extensive interactions that stabilize the capsid to withstand the high pressure that comes from accommodating such a large genome. Science , this issue p. eaam6892
