Fig. 6.

Molecular arms in baculovirus and cypovirus polyhedra. Surface representation of the interaction between a central trimer and a neighboring tetrahedral cluster in baculovirus (A) and cypovirus (B) polyhedra. The tetrahedral cluster is represented in gray except for the molecular arms clamping the central trimer, which are highlighted in green and indicated with black arrows. As described in the text, these arms are the C-terminus of baculovirus polyhedrin and the N-terminal helix of the cypovirus polyhedrin.
