pubmed:abstractText |
The structure-function relationship of P. aeruginosa exotoxin A (ETA) was examined using synthetic peptides and genetically engineered ETA deletion mutants. Antibodies directed against synthetic peptides have allowed the identification of three ETA epitopes, two within domain I and one within the last 33 amino acids of domain III. In addition two distinct neutralizing determinants have been identified by antibodies directed against subclone products. One was associated with the amino-terminal half of ETA, the proposed receptor binding region. The second was associated with the carboxy-terminal half of ETA, a region previously not associated with receptor-binding. The amino-terminal subclone also offers potential as an ETA vaccine, since it produces a stable, non-enzymatically active product, effective in inducing ETA neutralizing antibodies. Data derived from these studies were used in a re-evaluation of structure-function relationships between ETA and diphtheria toxin.
