Figure 2. Stereo views of Cα representations of individual pertussis toxin subunits, in the same orientation as Figure 1a. (a)S1, (b)S2, (c)S4, and (d)S5. S3, which is very similar to S2, is not shown. The amino (N) and carboxyl (C) termini of each subunit are labelled and the Cα atom of every tenth residue is numbered. Secondary structure was assigned with DSSP [55].
