Table 2. Properties of reconstructions of virion, procapsid, and mutant particles of PRD1.

Particle	Resolution of Reconstruction	Radius of the Capsid Shellsa	Radius of the Inner Membranea	Thickness of the Membranea	Relative Membrane Intensity Compared to that of the Capsid Shellb
Virion	12 Å	283–322 Å	223–260 Å	37 Å	∼100%
Procapsid	14 Å	281–322 Å	200–245 Å	45 Å	∼80%
Sus621	19 Å	281–325 Å	198–243 Å	45 Å	∼75%
Sus526	22 Å	281–328 Å	203–240 Å	37 Å	∼69%
Sus42	18 Å	281–328 Å	203–240 Å	37 Å	∼62%

^aDetermined at full width half the maximum of the peak.

^bBased on radially averaging the central section of each reconstruction and comparing the averaged intensity of the membrane layer to the capsid layer.
