Keyword - Viral genome packaging (KW-0231)

Keywords navigation



Protein involved in actively packaging the replicated viral genome into a protective shell or envelope. Such packaging proteins are present for example in adenoviruses, herpesviruses and tailed bacteriophages. In bacteriophages, the packaging proteins complex is involved in recognizing and selecting a neo-synthesized viral genome in order to translocate it into a pre-assembled empty procapsid. DNA cleavage is sometimes coupled to genome packaging as well as maturation steps that induce structural changes in the assembled capsid.
