Polyhedrin
For the three dimensional shape, see Polyhedron
Polyhedrins are a type of viral protein that form occlusion bodies, large structures that protect the virus particles from the outside environment for extended periods until they are ingested by susceptible insects. They occur in various viruses including nuclear [polyhedrosis virus]es and granuloviruses. GVs contain one virus particle per occlusion, whereas NPVs package about 5–15 viruses in each occlusion.
