Structure of the tetragonal surface virulence array protein and gene of Aeromonas salmonicida.
The paracrystalline surface protein array of the pathogenic bacterium Aeromonas salmonicida is a primary virulence factor with novel binding capabilities. The species-specific structural gene (vapA) for this array protein (A-protein) was cloned into lambda gt11 but was unstable when expressed in Escherichia coli, undergoing an 816-base pair deletion due to a 21-base pair direct repeat within th...
متن کاملPorphyrin binding by the surface array virulence protein of Aeromonas salmonicida.
Congo red binding by virulent A-layer-containing (A+) and avirulent A-layer-deficient (A-) strains of Aeromonas salmonicida was examined. Congo red binding to A+ cells was enhanced by salt and thus hydrophobically driven, but at low Congo red concentrations binding was salt independent. Congo red was bound by A+ cells by a kinetically distinct mechanism (Kd, 0.25 microM) which was absent in A- ...
متن کاملImmunoglobulin binding by the regular surface array of Aeromonas salmonicida.
The cell surface of Aeromonas salmonicida is covered by a regular surface array composed of a single species of protein, the A-protein (Phipps, B. M., Trust, T. J., Ishiguro, E. E., and Kay, W. W. (1983) Biochemistry 22, 2934-2939). The array, known as the A-layer, is the key virulence factor for this organism. Cells containing the A-layer specifically bound rabbit IgG and human IgM with high a...
