Assembly and budding of a virus from a membrane microdomain. Viruses have an outer protein shell called a capsid which surrounds the viral nucleic acid. Enveloped viruses, such as HIV, have an ...

Using the vertical β-barrel major capsid proteins and ATPases related to known viral genome-packaging ATPases as examples, we can now re-evaluate the classification of viruses and virus-like ...

The basic components of a virus are genetic material and a protein shell, called a capsid, that surrounds and protects the fragile nucleic acids. During the life cycle of a virus, the genetic material ...
