Viral capsids are composed of multiple copies of one or a few gene products that self-assemble on their own or in the presence of the viral genome and/or auxiliary proteins into closed shells (capsids). We have analyzed 75 high-resolution virus capsid structures by calculating the average ...
Figure I. Reovirus Capsids Are Modified during Entry. The viral capsid is composed of eight proteins: σ3, μ1, σ1, σ2, λ2, λ1, μ2, and λ3. Proteolytic modification in endosomes results in the conversion of virions to infectious subvirion particles (ISVPs) and then to ISVP*s...
The long-term presence of viral genomes (DNA or RNA) in a cell without any evidence of virion production. Capsid Proteins that encapsulate viral genomes. Capsids are rigid, highly structured and are similar to crystals with a defined symmetry. The size, shape and symmetry of the capsid can ...
For example, parvoviruses have viral capsids containing one or two major proteins are simple while viral capsids of picornaviruses are complex and these complex viral capsids showed diversity in protein layers which are encoded by many different mRNAs or viral capsid of picornaviruses is from a si...
Longitudinal transmission electron microscopic image of influenza virions. A negative-stained transmission electron microscopic (TEM) image illustrating 1918 influenza virions Full size image More commonly, viruses have an icosahedral shape where capsids are composed of 60 repeating identical subunits that ...
Viral capsids are often regarded as inert structural units, but in actuality they display fascinating dynamics during different stages of their life cycle. With the advent of single-particle approaches and high-resolution techniques, it is now possible to scrutinize viral dynamics during and after th...

The genomes of most DNA-containing viruses are inserted into preassembled capsid intermediates (procapsids) through adenosine triphosphate–driven mechanisms.27 In preparations of many icosahedral viruses, empty capsids (i.e., capsids lacking nucleic acid) are frequently observed, indicating that ...

The nuclear import of the HBV capsid is a tightly regulated process, since only the mature capsid is able to cross the NPC and release the viral genome. On the other hand, immature capsids are also able to penetrate the NPC [48]. However, they remain blocked at the nuclear basket of ...
