Fig. 4. The occlusion body is impermeable and poised for dissolution.

a Two polyhedrin molecules (red/blue) which form the dimeric repeating building block and position of tyrosine residues (pale green). Arrangement of the residues on the dimer and their resulting position in the lattice are shown. b Two sheets of the lattice (red/blue and pink/yellow) are shown from three orientations demonstrating that the assembled crystal does not contain any open channels.
