In
virology, a nonstructural protein is a
protein encoded by a
virus but that is not part of the viral particle.
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.
