Structure of human cytomegalovirus virion reveals host tRNA binding to capsid-associated tegument protein pp150

Abstract

Here, cryo-EM reconstructions of human cytomegalovirus (HCMV) virions reveal host tRNAs associated with the virion’s capsid-bound tegument protein, pp150. tRNA recruitment is mediated by the interactions specific for HCMV only, suggesting the explanation for the absence of such tRNA densities in related herpesviruses.
