Viral nonstructural protein

From Wikipedia the free encyclopedia

In virology, a nonstructural protein is a protein encoded by a virus but that is not part of the viral particle.[1] They typically include the various enzymes and transcription factors the virus uses to replicate itself, such as a viral protease (3CL/nsp5, etc.), an RNA replicase or other template-directed polymerases, and some means to control the host.
