Comparison of the predicted sequences of the C-terminal halves of the Rx1 and WU2 PspAs. The sequence begins at the proline A domain (amino acid 289 of the mature Rx1 PspA) and continues to the end of the protein. The individual sequences are contiguous throughout, with spacing added for clarity of alignment. Amino acids in the WU2 sequence that are identical to those in the Rx1 sequence are indicated by dots.
