TABLE 3.

Comparison of size and volume of SBPV particles determined in crystal forms 1 and 2

Crystal form Mean virion radius (Å)a Virion vol (Å3)b
1 140 6.385 × 106
2 139 6.386 × 106
a

Determined as distance of the center of mass of the icosahedral asymmetric unit from the particle center.

b

Volume of virion cavity calculated based on virion structures. The space occupied by the unstructured parts of the capsid proteins located on the inside of the capsid was calculated based on average amino acid volumes and subtracted from the cavity volume.
