Alignment of the B. pertussis (B.p) CyaB protein (15) with the M. xanthus (M.x) Orf2 translation (AbcA). The two proteins show 30% identity and 53% similarity. The activation domain fusion created in pADZ165a starts at Orf2 amino acid E572. Double blocks above the aligned sequences indicate conserved amino acids, while single blocks define gaps in the alignment.
