Figure 3.
Secondary autocleavage site of CA proteins. The interactions
between pro-segment and protein residues in Y202L, precursor
S170A, R226K, S170C, and E159Q. Those involved in hydrophobic
interactions in S170A are superimposed in a transparent
space-filling representation. Hydrogen bonds are indicated by
dotted lines, and water molecules are represented as red
spheres. The distances between the side chain of Glu-159 and the
backbone carbon atom of Gly-160 via WAT1 in Y202L and R226K are
highlighted by thick dotted lines.
