The crystal structure of recombinant baculovirus polyhedra.[1]
Symbol Polyhedrin
Pfam PF00738
InterPro IPR001746

Polyhedrins are proteins that form virus occlusion bodies, large structures (polyhedra) that protect the virus from the outside environment for extended periods until they are ingested by insect larvae. They occur in various viruses including the single nucleocapsid nuclear polyhedrosis viruses and granuloviruses. The structure of polyhedrin comprises multiple beta strands, three alpha helices, and two pi helices. The resolution is 1.84 Angstroms. Ramachandran Plot
