FIG. 4.

Nucleotide sequence and deduced amino acid sequence of the B. hyodysenteriae hlyA gene. The structural gene begins at nucleotide 78 at the underlined ATG codon and ends at nucleotide 312 at the bold TAA codon. The numbers refer to the DNA sequence. A potential ribosomal binding site (RBS) and Pribnow box are indicated. The singly underlined amino sequence represents the phosphopantetheine binding motif. The doubly underlined amino acid sequence is the N-terminal sequence derived from purified beta-hemolysin.
