FIG. 6.

Peripentonal regions of the outer (a to d) and inner (e and f) surfaces of SCMV capsids. Panels: a, nuclear B-capsid; b, diagram indexing features of note in panel a, where SCP is the smallest capsid protein present on hexons (gray outer portion of protuberance on top of the hexon subunits) but not on pentons, where the corresponding protuberance is markedly smaller and rounder; c, moderately tegumented cytoplasmic capsid; d, heavily tegumented cytoplasmic capsid. Also shown are the inner surfaces of the nuclear B-capsid (e) and the moderately tegumented cytoplasmic B-capsid (f). Bar, 10 nm.
