By electron microscopy and image analysis, we find that baculovirus-expressed UL6 is polymorphic, consisting of rings of 11-, 12-, 13-, and 14-fold symmetry. The 12-mer is likely to be the oligomer incorporated into procapsids: at a resolution of 16 A, it has an axial channel, peripheral flanges, and fits snugly into a vacant vertex site. Its architecture resembles those of bacteriophage portal/connector proteins.
