Amino-acid residues involved in biological functions of the cytolytic enterotoxin from Aeromonas hydrophila.

Gene - 14 Apr 1995

Abstract excerpt

Some amino acid (aa) residues within the cytolytic enterotoxin (Act) of Aeromonas hydrophila essential for biological activity were identified. Act is a 52-kDa polypeptide, possessing hemolytic, cytotoxic and enterotoxic activities. By deletion analysis, generation of anti-peptide Ab, and site-directed mutagenesis we showed that two regions in Act (aa 245-274 and 361-405) were very important for biological...
