Viral protein

A viral protein is both a component and a product of a virus. Viral proteins are grouped according to their functions, and groups of viral proteins include structural proteins, nonstructural proteins, regulatory, and accessory proteins. Viruses are non-living and they do not have the means to reproduce on their own. They depend on their host cell's metabolism for energy, enzymes, and precursors, in order to reproduce. As such, viruses do not code for many of their own viral proteins, but rather, they use the host cell's machinery to produce the viral proteins they require for replication.
