Table 2.

Surface area buried in dimer interface (Å2)

Protein Total CR1 CR2
PToV HE 2,563 686 1,877
BToV HE 2,044 661 1,383*
BCoV HE 2,075 910 1,165

*Reduction of the buried surface area in CR2 by ∼500 Å2 with respect to PToV HE is caused by Glu365, a residue that is unique to BToV HE (see Fig. S4).
